Interstate federation has clear advantages, like removing barriers that prevent people, goods, and money from moving freely between states. This would help create common laws, a unified monetary system, and better communication. Many believe that economic union, along with political union, is necessary to achieve these goals. The main reason for forming such a federation is to ensure peace by reducing conflicts between states and making the union strong enough to defend itself from outside threats. Historically, countries that successfully work together in foreign policy and defense have had shared economic systems.
Having a single economic system is crucial for effective foreign relations and defense policies. For the federation to handle international treaties, it needs control over economic activities, such as trade. Internal barriers between states can prevent the best use of resources and create problems for defense strategies, as local interests might conflict with the common needs of the federation. Economic separation can lead to strong local interests, which can create conflicts and weaken unity. Overlapping interests among different regions can help reduce these issues, allowing people to face the same challenges together. Without economic integration, political unity may not last long, showing that a successful interstate federation needs both political and economic union to stay strong and unified.
The absence of tariff barriers and the free movement of people and capital between states in a federation have significant impacts that are often overlooked. Individual states have limited ability to manage their economies since, with free trade, prices for goods will only differ based on transportation costs. Changes in production or investment opportunities in one state can quickly affect prices everywhere in the federation. Most economic policies aimed at helping specific industries rely on changing prices, but this becomes impossible at the state level within a union. Instead, states would have to provide direct subsidies, which limits their options for supporting producers.
States will also not be able to implement independent monetary policies. A unified monetary system would restrict the flexibility of state banks, likely leading to a federal banking system. Additionally, states may struggle to enforce regulations, like labor laws, without disadvantaging local industries compared to others in the union. In terms of finance, states will find it challenging to raise revenue through taxes that might push capital or labor away. Overall, the federation would greatly restrict individual states' economic policies and the power held by organizations like trade unions.
In a federation, the economic powers of individual states are limited, which means the federal government may need to take over responsibilities that states can no longer manage. One key area for discussion is tariffs, a form of government intervention aimed at protecting specific industries. These tariffs could be unhelpful if the industries they aim to protect still compete against each other within the federation. For instance, a tariff benefiting British wheat farmers would not help if Canadian or Argentine farmers are also included under the same trade conditions.
Another challenge arises when a tariff is designed to help one specific industry grow or shield it from competition. This type of protection requires sacrifices from other producers and consumers, creating tension and potential unfairness among different groups within the federation. In a national context, it is easier to justify such sacrifices because people may feel a sense of national pride supporting their local industries. In contrast, people in a federation may be less inclined to help industries in other states, as they do not share the same sense of community or nationalism.
Furthermore, the diverse conditions and varying economic development stages among the federation's regions complicate tariff agreements. What works well for one part of the federation may be seen as harmful in another, making it challenging to find a balance that satisfies everyone. This complexity could lead to resistance against federal legislation intended to regulate industries, especially if those regulations are viewed as unnecessary restrictions in less developed areas.
Additionally, central economic planning requires common values and ideas. In a federation with diverse populations, this agreement on values is harder to achieve. People might strongly object to decisions made by a centralized authority that does not reflect their local interests or traditions. As a result, the federal government's ability to regulate economic life could be more limited than a national government’s, making many forms of economic intervention impractical.
Lastly, the idea of a socialist federation raises significant challenges. Different economies, traditions, and standards of living create barriers to consensus on economic planning, making a unified socialist approach impractical for a diverse federation. In such a scenario, neither the central government nor the individual states would have the authority to impose an effective socialist economic system.
In a federation, some economic powers that are now managed by individual national states might not be exercised effectively by either the federation or the individual states. This situation implies a need for less overall government if a federation is to function properly. Certain economic policies must be handled by the federation, determined by mutual agreement on their use. If agreement isn't possible, the choice may have to be to avoid state legislation that disrupts economic unity. This lack of legislation may test if society is ready for a suprastate organization.
Existing federations show that just prohibiting specific trade barriers, like tariffs, is not enough to maintain unity. Individual states can easily bypass these rules through administrative regulations. Thus, the federation might need to hold general powers to prevent states from disrupting economic activities. Various constitutional protections in places like the United States help to maintain economic unity but face constant challenges from those pushing for more state control.
While some government functions will still be effectively managed by individual states, many powers will be diminished as responsibilities are transferred to the federation. Local units may actually handle some functions more efficiently than larger sovereign states. A federation should focus on creating a supportive framework for individual initiative without intense daily interference. The economic policies should have a long-term focus, avoiding immediate, short-sighted solutions that favor powerful interests. However, discussions about specific positive economic tasks or monetary policies in a federation would require more detailed examination than can be covered here.
For an interstate federation to succeed, it needs a liberal economic system, and creating a strong international legal order is crucial for this success. Historically, liberalism did not fully succeed because it teamed up with nationalism and socialism, which conflicted with its core values of freedom and cooperation across nations. Today, both nationalism and socialism are challenges to liberal democracies. However, there is hope for a return to true liberalism that focuses on its original ideals. This form of liberalism is not linked to any specific political party and used to unite people in Western democracies. For international democracy to work, the government's powers should be limited to areas where everyone can agree. This implies that democracy functions best when the government does not interfere too much, focusing on preventing war and conflict. It is important to recognize the challenges facing this goal, as understanding these difficulties can help create effective solutions for building an international organization based on shared liberal values.
