If you come from a family with moderately high income give them this spiel, worked on mine, "Im working my ass off in school and really want to succeed, but a lot of my friends are getting jobs (Give examples) and theyre making money but they dont have time to focus on school, I promise I'll work my ass off for my GPA but is there any way I could get an allowance so I can afford cool stuff while focusing on school 100%, and it can be suspended if my GPA is below a certain number (set number with parents)" You can also promise to get a job in the summer. This worked for me and I get $50 a week now
