Basically (and I’m not an expert here), the Uber rich get tax free spending money without taking big taxable salaries by leveraging their assets for super low interest loans. Current tax codes don’t consider these loans as taxable income, but they’re being used for the same things us peasants use our income for. By considering these cash flows as taxable, billionaires wouldn’t be able to hide behind the “it’s net worth not liquid income” bullshit these use to dodge taxes.
Interesting, I’ve read / heard that cats heal themselves through purring but even that was just a guess with the next leading theory being that they’ll purr when in pain to comfort themselves.
