I would not back end load, I would front end it.  You should study whatever interests you but if you want to study something where employment is rather restricted TUITION should be higher.  Why?  Because education is subsidized by taxpayers.  So if you want to study for expertise that will not pay back you should pay more.

A BA in Sanskrit? No subsidy.  Pay the full cost.

A nursing degree.  Full Subsidy.  No tuition fee. 

etc.
