There's nothing wrong with not having a degree, however it's something that there's no reason to not strive to attain. America's college education rates are appalling, we're going to be a third world country in a few decades if we keep going in the direction we've been going in.
The era of a middle class lifestyle being readily attainable without college has basically ended.
There are a few industries left in this country that focus on vocational training but they've been dwindling ever since WWII.
Would I like industry to return to this country? Would I like sustainable blue collar jobs that provide a decent standard of living to be accessible for everyone? Of course! Everyday I go to work I walk through the burnt out remains of American industry and see the poor few that haven't been able to make the transition. I know the pain of deindustrialization intimately- and that's exactly why I think it's so critical that our young people be pushed to get the best education they can get. Because their chance today of becoming a welder or a die cutter are smaller then they've ever been- particularly if they live in the inner city.
