First off, you are way overestimating the average college student's debt upon graduation. For 2011 grads, the average debt was $22,900, the highest ever. As you can see, that is no where near your estimation of "100s of thousands of dollars"! Secondly, who promised you a fair world? Life is not fair, get used to it. People will get admission spots, internships, jobs, promotions, boyfriends/girlfriends, etc. that you feel you deserve. It is just the way it is. The best way to secure a future job is to gain relevant work experience while you attain the education that you need to perform that job, whether that job be a doctor, a lawyer or an Indian Chief. As far as loans, you need to be very judicious in the amount of debt you incur, particularly for undergrad. As far as a non college grad making more money than a college grad, good for them! They obviously found something that works for their particular situation.
While I do think it is important to be cognizant of the issues you bring up, it is a mistake to dwell on them. The best that you can do for yourself is do well in school, get relevant work experience and do your very best to minimize your debt. When the time comes to apply for jobs, cast a wide net. Plan for the worst and hope for the best. Good luck to you!
