Heres the deal. A doctor went to college for a minimum of 4 years undergrad. Today that costs close to $20k/yr everything included. You have to be at the top of a class to be accepted to med school, thats i think 3 years, maybe 4 i cant remember. Which again is big bucks, then find a residency for 3 more years or so then another if they specialize, say eye surgery or something. Then they have bills sometimes upward of $.5million to repay.
Oh and there is the thing about your life or welfare is in thier care. If the carpenter screws up your out money and a good job, unless a total hack he could cause a house to collapse?
Take me for example, when i was 14 i was working for a trim carpenter/cabinet maker/custom stair builder. I worked there through the first few years of highschool. then went on to the retail type stores. I was interested in carpentry and building, but more to know how to do it for my self and projects. Once in it and when i was doing it i realized i never wnated to be a builder/carpenter. BUT had i wanted to and went straight into it after high school by the time my current self graduated college with all my degrees 6 years, my carpenter self would have had 6 years full time. In that time i think since i am a quick learner that i would have been a decent carpenter, no expert but could definitly handle many jobs on my own. And if in an area where a "decent carpenter" could make $40+/hr say after these 6+ years i was working instead of in college. Point here is i wont ever make $60/hr in my current line of work, and i have 2 college degrees. I also know a college degree is not an automatic ticket to making that kind of money but something is seriously wrong when a "above average" carpenter makes more than a person like me with 2 degrees, graduated #2 in my major and runs a multi million dollar program?
