Need to prioritise! Blimey! Round here flats cost upwards of. £250k. Not a house, a flat.
The average salary in London is £35k. So if it takes ten years to get to that point, you'll have to get a mortgage about eight times your salary to afford the flat, not house. Not everyone has parents who can lend the deposit.
If you're living in London, a flat share is probably around £500 plus bills. Then you've got rail fares, which is about £250 a month, utility bills, £100, council tax £100, food + work lunches £200. Then they'll need to save for their pension as there won't be workplace pensions and minimal state pensions, so another £100 for that. Even if they don't go out, buy anyone a birthday or Christmas present, have any kind of holiday, never buy a coffee etc there's only about £500 per month to save for a deposit on a £25k salary. It's going to take a hell of a long time to do that.
I on the other hand am not much younger than you, maybe five years, was able to buy a housing association flat (yes they existed for single people then!) on my meagre public sector salary at the age of 23. Okay I had to have a lodger, didn't go out much, etc but it was possible and I didn't need a deposit. It nearly doubled in value by the time I sold it.
We all knew about the pension changes, so I don't know why you didn't. I knew I had to have my own pension because for years it was obvious we couldn't afford to have pensions from the age of 60 that would allow people to live very comfortably. If people were prepared to pay much more tax it might have been more possible but this is the generation that consistently voted for Margaret Thatcher's low taxation and selling off our utilities, so things now cost more. They're also voting for Boris Johnson and Brexit, so we're going to be even more stuffed.
I feel sorry for younger people now and think that older people have overall had a pretty good deal in comparison.
