Are my parents being dumb?

I'm 15 and I live with my mom and my stepdad. Were pretty rich but they ALWAYS complain about how I don't have a job when I can't even get one. I'm legally allowed to but who will hire a fifteen year old ? And whenever I'm at home to much they yell at me and tell me how I have no life and when I hang out with my friends they yell at me for never being home. It's summer and I just turned 15 a week ago and I'm trying to enjoy it but they're already trying to cram getting a liscense down my throat. And when I tell them I'm not old enough they say they're making me get a hard ship liscense. What do u think about this and what can i do to make them shut up -_-
