After tax that would get you one year at a good boarding school.
Average salary in the U.K. is something like 25k so using that as a basis 70k is probably not totally illogical being almost 3 times the average
As your earnings increase so do your outgoings, bigger house, nicer car, nicer holidays. You need to get over 500k to really feel flush, anything over that just goes into the pot for the supercar collection
Lol. Probably worth pointing out I don't work for hmrc. The civil service never appealed to me
