Should I take a loan?

People tell me to this all the time. It seems like they dont even give the other side of the argument. People just tell me its a good investment. I am like how is it a good investment? They dont teach anything valuable. It seems like the "good" "important" jobs are the most useless jobs. All people do in thier high class job is sit at a desk for 6 hours. Half of it they waste on eating coffee and buns. I would like to be a builder. If I was not building for immigrants and jews.
