Yes I know, your least-favorite idea goes here. But seriously, someone must have come up with the concept before. Like a bad get-rich-quick scheme could fall into this category, where joining the scheme makes people lose money and become more desperate, so they become more likely to do desperate things like invest more in the scheme.

There’s a certain amount of Gambler’s Fallacy in this, too: I’ll keep going, because it’s going to turn around.
Yeah, I think it’s the really the Gambler’s Fallacy, even if OP doesn’t describe gambling. It’s the idea of “It’s my turn for success to come soon – I’m due for my turn!”
Feels like there ought to be a term… it’s kind of a mix between “vicious circle”, “feedback loop”, and “echo chamber”.
Sunk cost fallacy is probably the most obvious one that springs to mind. Not unlike gambling in a sense, people feel they just need one big payout to win it all back and then some, so they keep betting, hoping that this time things will go in their favour.
