I wonder how much this will happen? It seems that qualifications from cheaper institutions are always valued lower than those from more prestigious and expensive ones. I doubt that this is entirely due to the more prestigious universities having harder course content.
In the UK there seems to be a strong correlation between how valuable a degree from an institution is perceived and how many "posh people" attend a particular institution.
I've often wondered how often "we want somebody with a degree" actually means "We want somebody from a particular social class". The labour government's answer to this was the ensure that more young people got a university education from across that social spectrum but this doesn't seem to be reflected in the employment figures of young people.
