You should use "others peoples money" in the right situations if you are responsible.
Why spend $2000 on a tv when you can spend $2280 over 2 years (assuming 7% interest). Why tie your liquidity up in one shot.
Credit is perfectly fine you just have to know how to use it which most people don't(including me at 18)
lol, so you wanna throw away $280 bucks and have a payment every month for two years, for a fucking tv no less. Go ahead and do that, I'll pay cash for mine. No payments and more money for me.
