I know plenty of people making well over that $150k level living paycheck to paycheck. If will be a miracle if all of them don't go bankrupt and that $1500 check wouldn't be enough to solve problems for a single one of them even in the short term.
The 100% unemployment for 4 months and expansion of when you can apply that was added to the bill yesterday will save more families than the direct payments. Those will mean a lot to lower-income workers that need immediate short term help.
