In the article Elon Musk said that we (and by we he means us) have to reduce spending to live within our means. LOL. This from the guy who sells $100k cars.
Probably realized he can't sell a lot of those anymore.
He could sell a bunch of Tesla stock, crash the entire US economy and then buy a whole lot of whatever he wants because everything will be discounted (including Tesla, he could just rebuy his stock for a fraction of the price)
Rich people LOVE economic downturns. Best time to make money is when everything is on sale, just need to buy and wait. Stocks, property, everything.
