The author lists four within the past four years:
"1. The election of Trump;
2. Covid and the anti-science response--State and media induced mass hysteria;
3. Establishment sponsored street violence; and
4. The electoral coup--notable, he says, both for its boldness and its success."
and
"Since mid-March of last year, while Main Street suffered economic pain from the Chinese flu lockdowns, the wealth of U.S. billionaires grew by a whopping $1.3 trillion. Here is how the top five fat cats made out in terms of wealth increase and as a percentage growth in their wealth during this past year of pain:
Jeff Bezos — $76.3 billion (67.5%)
Elon Musk — $158 billion (642.4%)
Bill Gates — $25.7 billion (26.2%)
Mark Zuckerberg — $41 billion (75%)
Warren Buffett — $24.2 billion (35.8%)
How can this be justified? It can't. What it shows is that the government and the Fed are more concerned with rewarding the top 1 percent than they are the ordinary Americans."
