Mumsnet is not typical of society at large, though. If you believe everything on there, the average poster has a household income of £100k with one parent at home, wears designer clothes, sends their children to private school and went to a 'top' university where they got a first. Either it is a very specific demographic or there are a lot of fantasists
.
I find some of those threads hurtful, but I don't think they are representative of the feelings of young people as a whole. Also, a lot of MNers are buying houses of their own - do they plan to give them away when the mortgage is paid off? I don't believe that anyone really thinks that people should be made to give up the house they have paid for to make room for a family - there would have to be some sort of communist revolution with housing allocated by the state for that to work, and today's young people would fall foul of that sooner than they expect.
I do think that this generation have a very hard time though, and that having been, on the whole, brought up to expect life to keep getting better, they see things differently than perhaps ours did. House prices are comparatively higher now than 40 years ago, and it is true that in some areas people have 'made' money simply by living in a house they bought relatively cheaply. I know it didn't feel like that at the time, but a lot of families did manage on one salary in the past, whereas nowadays it usually takes two to get by, and the cost of childcare is astronomical. Things must seem unfair to them.
Life chances differ even amongst parents of young children. My sister's children are 10 years older than mine and have similar level jobs, yet they were all able to buy houses much younger than mine have. Their rents were cheaper when they started out, so they could save more, and the houses they started in needed a smaller percentage of their salaries than would be the case to buy the same houses now. In another ten years things may be worse again. There really doesn't seem to be a lot of hope for young people today.
Of course it's not our fault though, and I'm sure that most young people don't think it is.
