Your surpossed to grind when your young so you can live a "fuk u" lifestyle as a man. If your past 35 still having to "explain" yourself or still doing the "mickey mouse act" your have only yourself to blame.
Also, yeah construction jobs, ie. jobs that dont require a whole lot of brain power or jobs with out a college degree are going to be filled with mental midgets. Any sane man grows out of these type of jobs in his early 20s. I remember working these type of jobs when I was 18 and realizing what a "fuk up" in life you had to be to work these type of jobs, and I was already a C, D student in High School, so I can only imagine the type of mental midgets you have to work with. Having to dumb yourself down everyday in order to function effectivley at work is a recipe for misery.
As long as your around these "fuked up" jobs your going to have problems. If these midgets get any hint of intellect or confidence they see it as a threat and their only instinct is to go ape sh1t. Best to find a new line of work.
