Except for people who simply don't have 60€ a month easily, so they're left out. Also, it will absolutely not stay at 60€, it will become more expensive each year until the local tickets are cheaper again - defeating the whole purpose (if it won't be reverted outright after the next election, which the conservatives will win).
I'm not saying it shouldn't be free like in Luxembourg, just made the comparison with how it has been for decades until the recent 9€ experiment and now ~60€ subscription. It's already a lot better than it used to be, even if it's not perfect
Do you know how it works, actually, if you need to get to work but can't because of the cost? If you can't afford 60€ then you also won't be able to afford a car that costs probably >3x times as much for a barebones old model when you include the necessary insurance, road tax, and fuel. Bürgergeld pays your rent afaik but do they front e.g. costs when you get a job to actually get there until your first paycheck? Can one apply for a public transport subscription in low income situations?
