Guess it depends on what is the definition of a tinpot degree. If its a degree that doesn't lead to some job specifically then there is a lot of degrees that are tin pot.
If it's a degree subject that's supposed to be easy then a lot of it depends on where you do it. At the top universities no degree is really easy (some easier than others granted), but it's quite different at a lot of the newer ones. I had friends who did almost same degree as me (economics + politics
) and it was a bit of joke to compare what they did with what was required of us.
As someone that is quite pro university (tuition fees were introduced the year I started fwiw) I do think higher education got expanded too widely and too quickly and would like to see some funding/resources go towards those who either are not capable or inclined to go down the university route.
It's not for everyone and I don't want a US style system where everyone has a degree and its value is massively diminished (could argue this has happened already).
