I'm not quite sure what you're saying. Is the problem the fare evasion or the disproportionate amount of money spent policing fare evasion, with the collateral benefit of terrorizing the citizenry?

Now that a progressive beat a centrist in a high-profile contest where the party establishment tried and failed to stop him, the talking points identical to republican propaganda come out.

as a non-american looking from outside, if NYC already taxed the rich for a lot, then to me the next sensible logical thing for the mayor to do is manage the apparently already lots of money to better use and making his platform come true. to me whatever NYC is doing that sounds like mismanagement of tax funds

Yeah, someone has to pay for it all - the WEALTHY people and corporations who benefit by the infrastructure. They get all the rewards of the system, but they expect someone else to pay to maintain it, too?

If they need to pay half of their fortunes to keep the other half, they'll be just fine. If they refuse to cooperate, we'll just take it all.

The wealthy have a choice for the next stage:

Trickle Up Economics, in which they'll still end up with the money in the end, but it greases the economy along the way,

OR

Robin Hood Economics - Take from the rich and give to the poor. The problem with this one is that it will be VERY uncomfortable for the wealthy.

I'm good with either one.

You’re already paying for it, you get that, right? The thing is that EVERYBODY needs to be paying and the ones that have the most bend over backwards so that they can give nothing back. The fact that you say what you’re saying while New York is host to some of the most wealth in the entire world is a disturbing illustration of the problems and solutions at hand.

"shrinking population"

Okay so you didn't even do a iota of fact checking here. It's growing. And it always has.

That's where actually taxing the rich comes to play.
