The American economic system during these years would most closely resemble the ideal of capitalism. Capitalism had not been around for long before it was implemented in the United States. This system focuses on certain ideas in particular, such as free markets, free trade and private ownership. Moreover, at this point in time, many of the ideas of mixed economies had not been adopted yet, such as subsidies and quotas.
During the 1800s, the economy of the united states was considered small and still developing, largely agricultural. This provoked the capitalist to begin working through the Laizes Faire method in the attempt to alleviate the status of the economy. The answer would have to be capitalism.
