Reasons why the United States’ economy shifted from a subsistence economy to a market economy?

A subsistence economy is an economy directed to basic subsistence (the provision of food, clothing, shelter) rather than to the market.[1] Henceforth, "subsistence" is understood as supporting oneself at a minimum level. Often, the subsistence economy is moneyless and relies on natural resources to provide for basic needs through hunting, gathering, and agriculture. In a subsistence economy, economic surplus is minimal and only used to trade for basic goods, and there is no industrialization.[2][3] In hunting and gathering societies, resources are often if not typically underused.[4]

since most of current immigration into the u.s., both legal and illegal, is coming from latin america. it would be very difficult to imagine or rationalize a country my fellow citizens are trying desperately to flee into, would pose a threat to my prosperity or freedom. since the u.s. has a long history of intervention, but no record of permanent occupation, i would not feel oppression is the main objective.  

the largest free trade nation, along with the largest gdp in the world wanting to expand it's economic policy on us, and including us, could only be positive. the u.s. government has no interest in, or way of simply forcing american culture on us. and has no track record of it. other nations that adopted american social culture, or "americanization" did so voluntarily, mainly through the choice of allowing american businesses and u.s. citizens to come into their nations, as free operatives.

i think it’s will be a yes
