abouteve - most people spend to their limits, just look at footballers' wives etc.
So, generally the more you got, the more you spend. We have a HUGE GREAT BIG mortgage, so over hald DHs' salary goes on just the mortgage, despite not living in a MASSIVE mansion (SE house prices...)
YES, we could have moved to a smaller house, but wanted the investment for our future / pension.
Now with the recession no-one is buying houses, we're tied in with a fixed rate mortgage (we are risk averse people) so the costs can't go down, plus we're in negative equity anyway so would be in a lose lose situation if we did try and downsize (the best way to save money)
We are screwed, CB keeps us in the black each month as bigger house = more bills, including council tax (which is totally fair) - unless I can get a job over the next couple of years, unlikely as I work in education and the likelyhood of a recruitement drive over the next few years is slim to insignificant.
Also - think about the amount of tax that you pay. For every £1.00 you earn over the higher threshold, you only get to keep 60p, minus the National Insurance, minus any pensionable contributions, which most higher earners make. This is why we need to start discussing WEALTH in terms of NET income, not GROSS income, as GROSS income is very, very misleading...
Plus we need to look at the MODE wage, not the AVERAGE (MEAN) wage, which is often skewed by VERY high earners (eg the premier league footballers...)
