How exactly does RSU comp at a public company not help buy food at the supermarket or anything else? These are not options or illiquid shares, it really is the same thing as having a much higher salary. The only real difference is that your total pay fluctuates with the stock value. But even an enormous drop in stock value would leave you taking home real money.
Vesting is monthly (for the FAANGs I'm familiar with), you can even set it on auto sale to automatically sell your shares as they vest and just take the cash every month if you never want to see stocks. I feel like I shouldn't have to explain that publicly traded stock is highly convertible for cash!
