What was the post-War of Independence system of the United States like?

After the war, a bourgeois democratic republic was established. We can say that the United States at that time began to develop very progressively. There were no emperors, kings and noble nobles who in every possible way tried to preserve the current system, so as not to lose wealth and influence, which greatly impeded progress. Thus, the construction of a capitalist society began rapidly in the United States: factories, factories, banks were opened, railways were built, and so on.
