The Democrat party has always proclaimed itself the party of the workingman and the little guy while the Republican party was always painted as the party of the rich and big buisness corporations.
The super rich saw which way the wind was blowing and rather then wait for the coming Marxist revolution to overwhelm them and possibly put them up against a wall, billionaires: like Mark Zuckerburg, Jack Dorsey, Jeff Bezos, and Bill Gates et al. who aquired their outrageous wealth through via free market capitalism and entrepreneurship decided instead to join the Marxist revolution, and feed the crocodile in the hope that they will be eaten last.
Billionaires and millionaires promote, embrace and fund Progressive causes like “climate change” in the hopes that their total hypocracy will be overlooked and the mobs with torches and pitchforks don’t come after them.
