Dentist

I would have given you a red x because your not a "DUMB" truck driver.
A experienced wheel man driving a 18 speed with a 100,000 plus load is a skill

A person wanting to become a dentist or doctor needs to have a college degree in the sciences, a biology major and they need to have very high grades.
They then take their M cats for medical school or D cats for Dental school. If they pass and depending on a lot of factors they can apply to a school of their choose.......There is a significant fee for each application, in the hundreds of dollars and its non refundable
If you have the grades you get accepted and its very competitive
Im not sure what the schooling costs but by now its probably six figures per year (in fact it is)
Plus all your living expenses
Banks loan out the money just like a mortgage, takes years to pay off student loans
Working while your attending school is impossible as a student is studying day and night
When graduating than its a residency were the salary is very low
If a dentist wants to be a specialist its another 2 to 4 years after graduating dental school
A periodontist does another 4 years of training as does a orthodontist to name just two
So that's 8 years alone after college learning and making very low money and many hours studying
Most dentists wind up working for someone, as far as I know they make money on the amount of patients they see
Some might become associates for another dentist or buy into a established practice, which means they shell out even more money as becoming a partner isn't for free
Some start their own practice, the cost of renting a office or buying a place, not withstanding, id say setting up a practice could cost half a million for a modest practice.......Than their is the staff which is another issue all together
Thats one reason dental work isn't cheap

Just posted above what I paid between this year and last.
