DH has two sisters, one brother.
DH went to uni, got a degree, got a good job. Received no help from PILs (as they didn’t want him to leave their hometown).
Brother went to uni, dropped out and returned to hometown to live with PILs. Works shit jobs, leaves them all the time, funded occasionally by PILs.
Older sister never left PILs hometown, left school at 16, worked for a year, pregnant as a teen, had babies until she hit late 30s, funded by PILs and occasional work.
Younger sister left school at 16, left hometown to live with boyfriend. Lived in squats and benefits mostly. No help from PILs. Over 10 years later decided she wanted the life DH had. Went to college, started at the bottom in an admin job, now looking at 40 and she’s done very well. Married boyfriend!
Younger sister is the only one who regrets her decisions. DH and younger sister are the only ones not receiving handouts from PILs. DH and younger sister are the only ones that own their own homes and have a secure (as much as you can these days) future.
It just depends. But no handouts, don’t make it easy for her to flake.
