Well... multiple things here.
If you're in, say, finance, you can't just go and move to some flyover state and work remotely. You need to be around NYC (US), LON (UK) or FRA (EU).
If you work some service job, say you work retail, okay. But... imagine what happens to NYC when all the people doing the menial work keeping the city alive (have to) move away? Whoops, now everyone is going to drown in trash and feces!
It is vitally important for any city to have enough adequate housing for all levels of income, otherwise it falls apart.

That's not a "the poor middle class folks in NYC need help" story, that's a "the rich folks of NYC need folks to serve them" story. They're welcome to strategize however they like to incentivize people working there. Manipulative heartstring tug are not welcome however.
Maybe after they have to look at piles of trash everywhere, the employers (I'm guessing that would be the city) will learn to pay them what they are worth.
As a result, NYC like living is basically out of reach for the majority of the people who might otherwise want it. Nothing against Indiana, but if what you're looking for is bustling megalopolis living, I don't think Indianapolis is going to cut it. And your choices in the US aside from NYC are very limited.
