I recently had a fellow, doctoral co-worker poke fun at me for planning to leave the sciences. I told her if I had been truly smart and become a plumber or an electrician, I'd be on track to retire comfortably in 10 years; not have zero chance of retirement. I recommend the trades to anyone anymore. Engineering or comp sci are also pretty solid. There's no reason to idly support the Marxist indoctrination camps.
