That is some very black or white, us or them, red team vs blue team thinking. It's very interesting that you immediately jump to that conclusion when I am not even from the US at all. The answer to your question is absolutely not, and the fact that it's a "world economy" doesn't and shouldn't mean any people are obligated to do business with and accept the controlling interest of literal monsters fueled by oil and oil money. Ethics must also be allowed to control the economy, not just money. The world's financial systems have consequences beyond just the economy.
