These posts are idiotic, there is no "they" unless you are talking about the millions of investors who put their money into mutual funds or etfs every year regardless of market levels. This is the kind of conspiracy bs people believe in if they don't understand what stock markets are and who actually owns the companies listed on the stock market.
Let me clue you in....The Central Bank runs the markets. Not the millions of investors. They spent 4 trillion on this run. Wake up Mr. clueless.
