No need to talk down to people, you're comment seems very condescending. But maybe not, you can't tell tone via type.
Anyway.
Yes it did occur to me but first of all, if I couldn't get approved for a minor loan because of bad debt chances are that I wouldn't get approved for a credit card. Second of all, I chose not to use debt or "establish credit". I chose instead to clean up my debt by paying everything off not add more credit. The only debt I have remaining is my auto loan because what I did instead of incurring more debt is work hard, very hard, took on a second job, sold things and paid off thousands of dollars in debt in the last two years ON MY OWN. I'm more proud of that, thank you very much.
My credit score has improved greatly since two years ago simply by continuing to pay bills on time and pay off debt. This is what works for me.
