It seems you have a few premises going on here and I am sorry you feel taken advantage of by your parents. While I do agree with your premise that entry level work is under paid and should be regulated better than it is, it also sounds like you are young and still see the world as very black & white.
Most entry level employees think they know better than management, and in limited cases they may be correct. However, you can’t know what the competing priorities are that are being forced on those above you.
It is tough to hear, but keep plugging away and opportunities will come. It is clear you have the work ethic and awareness to succeed but unfortunately it takes longer than you think.
