Okay, yes, $100,000 does veer into middle class if not upper middle class territory but there are areas in the country with quite high living costs like California where housing prices appear to be through the roof.
That said, it might be fair to just raise taxes but focus on those in need, the poor and working-class (in my perspective, I think there are moderate-income folks (think working class people) who could use the help but make too much to qualify yet they’re far from comfortable or stable. One could make an argument, that these people were definitely trying to an extent, yet some help could be nice. Maybe something to support economic security, as the richest country of the world, can we not afford that, at least a piece of that?
One experience I had was during my high school years where you had students paying for AP Tests, you had people who couldn’t get fee waivers due to free and reduced lunch and thus had to pay the price, taking multiple classes it ended up adding up. It wasn’t the most pleasant experience. Granted one could also argue that having “skin in the game” provided decent incentive to students and that fees gave students and families an opportunity to better deliberate their options (especially since high school life can seem stressful balancing classes, extracurriculars among the other factors in their lives).
