This is so because the economies of each state would be significantly less decisive than the American economy in general, and except for specific cases such as California, Texas or New York, the rest of the states would have a notable lack of resources that should be compensated through unfavorable trade treaties with other countries. In addition, the demographic and political weight of each state would be much smaller, which would not be able to obtain the same commercial benefits that are obtained today, which would generate a greater lack of jobs and a decrease in the quality of life of the citizens.
