i live in DC. Same problem. For jobs they would normally hire seasonal college kids they are hiring full time adults because those adults cant find other work. For internships, they want alot of college experience rather than a graduated high schooler or a freshman/sophomore in college.
for me, i got hooked the hell up. at my house in long beach island, NJ, my grandpa is good friends with this dude who owns a marina across the street from my house so i got set up there and im working at a gas station some nights, just because im bestys with the dude who runs it
