Agree. I answered a few of your questions in the other forum too but now I also fear you need more basic info. If you want to be wealthy, do not do PT. Yes, the debt load is too high generally, yes the salaries are too low for the education. Yes, we still have fantastic PTs practicing but they aren't in it for the money. And money will be a little tight for many the first years out. I made more working before I went to PT school (with a bachelors) than I will make after. But that's OK for me because this is the best fit for me. And I can be a great help to my patients because I will like what I do and I believe in it.
Serious advice, if you like science and math and want to make money, look at some engineering fields, economics, computer programming. Heck, even healthcare management where you will get people interaction too. Or pharmacy...they have their own issues but starting salary will beat any one here if that's your goal.
