Once you get above extreme poverty/unemployment, there are roughly two kinds of households in this country, those which live paycheck to paycheck and those who aren't counting down the days until the next direct deposit shows up every month. Even people who live paycheck to paycheck might be living pretty well, that is those paychecks might be pretty good but they've made housing/transportation/lifestyle choices which still put them at the edge.
I doubt too many senators know what that's like, or know what it's like when you're living paycheck to paycheck and then suddenly no longer have a job.
...adding, commenters not getting my point, which is that even people who are decently well off often live paycheck to paycheck and have all of the associated stresses. I meant no judgment of such people (and in fact count myself among them most of the time).
