I agree that it's silly to say that you don't benefit from government spending at all. On the other hand there is often a real sense of not getting what you put in. I imagine especially so on a forum like this where many are professionals of certain industries with relatively high pay.

For example: public spending per person in the UK is < £10,000 per year, which is much less than I pay in taxes. And I would estimate that I'm well below average in terms of spending received: I don't have children, don't have any large medical expenses, etc.

Of course, my cost to society will rise as I get older, but on average I would estimate that I'm paying at least twice (and probably many times more than) what I'm taking. And yet the current trend is for half of society to say that I'm not paying my 'fair share'. I'm not sure what definition of fairness they're using, but it's not mine.
