I'm in my late 20s, and I do think it's really tough for people of my generation. It's all very well saying a pension should be a priority over even buying a house- but renting is very costly (as is having to move regularly) and can lead to people getting in a bit of a cycle of debt. My first priority is to buy somewhere to live for the quality of life benefits in the meantime.
In terms of pensions, I did pay into a pension scheme for a year and a bit at a previous job, and then I decided to career change into being a teacher. I'll start my NQT year next year and will obviously be paying into a teaching pension then. I can't really imagine myself teaching in my sixties, but then I can't really imagine what the world will be like 30-40 years from now anyway!
I do think using property as a pension is a risky idea (unless you are able to buy lots of properties)- people say they will downsize, for example, but that can actually be quite tricky- there are not that many smaller homes available to buy, and competition for them between first time buyers, investment landlords and downsizers is fierce in some areas! It can also be hard to find a home that's suitable for an older person's needs if e.g. they have mobility issues and most older people don't want to move areas away from their support network. Equally, to sell a property or rent it at market value, it usually needs to be in a reasonable state of repair- which can be hard to maintain as you get older.
I don't think house prices will crash- but I do think we are going to see a bit of a leveling off and maybe a slow decline in house prices. People in my generation struggle to buy, not just because of deposits, but also because of affordability criteria. If you are a single person and only allowed to borrow say 4x your salary, that really limits what you can afford. At the moment, there does seem to be a bit of a political shift against landlords and second home owning, so this may also have a bit of an impact on prices.
The thing I do have in my favour is that at some point I may get some inheritance from my parents (they are home owners and have decent savings and a range of investments). I'm not relying on this, as I know one/both parents may need care or they may need to use these assets to fund their own retirement- but it is a possibility.
I think this could end up being the big driver of inequality later in life for my generation- those who are able to inherit something, and those who aren't. I know quite a few people who have parents whorent or live in council houses, or who don't necessarily expect any/much inheritance due to their parents being in debt, or due to things like family breakdown where parents have remarried and so on. And, if the current situation continues, there will also be people who's parents assets are used to pay for care and so on.
I think it's a complicated situation with no easy answers, and I do agree that part of the problem is people living for longer with increasingly complex health needs- but I don't think the answer is taking steps backwards in medical science!
