It looks to be aimed at the type of people who see their own generation as selfish trash, and would be receptive to the “we’re looking for the real ones, join and find your peers” type message that the poster goes for.
But I doubt that lands with a lot of people. That younger generations are lazy, selfish, penny pinchers is not a view held by a lot of the people who actually are of those generations.
Might work if they were recruiting boomers, tho.
It makes sense that that culture attracted the exact type of people who treated this woman like shit.
