Your post sounds kind of leftist.
That post was pro American and not leftist at all. Marx believed in globalism and mass immigration because they destabilize society.
Conservatives support a "free market," which means one closed to subsidized foreign imports, illegal aliens who work illegally not just because the aren't here legally but also because they are often employed by employers who are tax cheats and who fail to observe American labor laws and regulations. A "free market" also means the gov should break up monopolies in airlines, cell service, banks, distribution, and many other areas that negatively affect almost every part of the American economy. It should also support by tax and import policies (and even sometimes direct subsidies) industries that are vital to US defense.
What it should not do is grant special favors to particular industries or bailouts without first bankrupting the recipient, taking ownership, and reselling it to new stock holders. If bankruptcy and foreclosure are good enough for you and me, they're good enough for GM, Boeing and the banks.
