Wyotech or other tech schools??

My opinion is do not pay big money for one of those schools to get out owing big money and only an income of 40,000 a year. Now days the job of being a mechanic does not pay well. Owning your own shop you will find at the end of the year you only make what you pay your help. Is it really worth the grief to run a business and make the same as if you worked for someone and didnt have the grief.
