I think that's such an unfortunate assumption, MsVestibule, that someone of your age but wasn't earning a lower salary automatically suggests they weren't particularly ambitious.
For example, if you working in the charity or arts sector, you can often not be earning large salaries but that doesn't mean they aren't ambitious.
I used to work in PR and when I was 26 was earning £30k (some sixteen years ago, which was pretty damned good). But, it being PR, I worked very long hours, which meant some days getting up at 6am and getting home at 8pm. So I built a nice nest egg but had no spare time to spend it and my social life wasn't the best. So, I'd have had the money you wanted, but you would hardly have spent any time with me.
I now work in the arts sector and earn £20k. I have my own flat (mortgage, but not huge). I work better hours, thoroughly enjoy my work which is varied and not run of the mill and have more free time to spend with friends or a special someone. I would like to move to another venue at some point but the pay won't be much better (unless I end up at the RSC or National Theatre)! Doesn't mean I don't have ambition.
Which would you rather have - someone with passion for what they do and enough to live perfectly acceptably on (on my salary I do manage to afford a couple of weekends away and a week abroad) and see them, or someone you hardly see but who brings home lots of money for you to spend?
Some of the comments on here seem very one sided and materialistic and it's very much about what a man can bring to the table rather than what TWO people can bring to the table TOGETHER.
