As of right now students get paid 20 Galleons and adults get 45 Galleons each week for having a job. Honestly it's a very low rate and there's almost nothing you can do with such a little amount of money even if you put it in Gringotts for rates.
I really do think it should get a little boost so it's worthwhile to have a job. I can earn 20 Galleons by grading four pieces of homework. If I'm lucky and they're short it takes less than 10 minutes to do so. I know some jobs may take more time than others but I spend about 30-60 minutes a week to write an article + Quidditch at the moment (Which also takes time quite a while). If anything, students should get 50/75 and adults 100/150 for having a job.
