Americans with incomes below $75k are getting the full stimulus ($1400). That's per person. What they consider a struggle range is a quite high bar, no? I wouldn't need a stimulus payment if I made half that much. I don't mean to critisize the stimulus or sound republican, just reflecting how high living standards are.
I have no strong political standing, and I still think 75k is a perfectly reasonable number when you bring all factors into consideration. Especially taking into account all of the people who have families and who need to support them.
