I don’t buy this whole “I went to university then trained and trained for years and years and now someone driving a van earns more than me, waaah” stuff. You should have done something else.
If I was unhappy with my lot but thought driving a van or whatever was easy money and lots of it, I would go and do that instead. There’s no point in being bitter about how much you earn, if you don’t like it, make a change 🙂
