You suggested that 4 year colleges not be free. Bone said why it was a bad idea.
You now respond that you should also fund vocational training?
You appear to have misunderstood me entirely, what I've been saying all along is that if you're going to make university free then vocational training should also be subsidised in the same way... You shouldn't fund one without the other, I thought that was pretty clear.
Also, what about people who have societally important jobs which don't require a degree? Like mechanics, plumbers, nurses etc. Why should somebody be paid to spend 3-4 years at university doing something like English or Media Studies when those people are out working their way up and supporting themselves?
In the UK plumbers, electricians, mechanics etc can make a hell of a lot of money, comparable to many doctors. You could also make the argument that those kinds of trades are just as important as doctors too so why shouldn't they get subsidised while others get free college worth many thousands of dollars?
No, the alternative is to also fund vocational training if you're going to make college free. Given that it's usually not the wealthy who go into vocational trades surely that would achieve as much, if not more, than free college for social mobility.
