No more loans for Liberal Arts majors.
A better solution - press colleges to defund the programs and actively discourage anyone from studying the programs.
You can fight on a college by college basis and make progress long before there’s a national, top decision like Poland’s.
You can cut off funding and support for the programs by not letting your kids study this and discouraging others from studying it.
Also tell colleges you will NOT donate to them after political suppression on campus and explain that is why you will not give them money. Example - alumni of a school telling the school they won’t donate because the school police did nothing while liberal bullies ripped up crosses set up by pro-lifers or permitted someone to deny others their free speech rights via cow bells, shouting and air horns.
