I'm a boomer, and while much of my adulthood was a struggle, I think things are worse now.
The biggest factor imo is the cost of housing. Rents are so high that most people can't raise a deposit until they're much older than my generation was, and the deposits are much bigger, relative to earnings, because of the absurd price of housing.
However, many of my peers couldn't buy until they were in their 30s, lots didn't learn to drive until they were late 20s/30s and couldn't afford to run cars anyway.
I was lucky enough to buy my first house for £24k on a 100% mortgage. But the interest rates were massive compared to now, I had had to have a lodger for the first 8 years to cover the costs and had 3 jobs at one time, to pay the mortgage. I didn't have a single item of new furniture until 16 years after I left home. Everything was 2nd hand, including my cooker, washing machine etc. I've still never spent more than £2.3k on a car!
Successive governments have failed to do anything about housing. Hardly any social housing has been built and rent has spiralled beyond belief. Demand for housing is rising because people are living longer and family homes are often occupied by single old people, like me. So I'm part of the problem. But after grafting all my life, and still being unable to afford to retire after 49 years of non-stop work, I feel quite entitled to stay in the 2-bedroom house that I've paid for.
When I die, most of the wealth in my house will go into a trust for my late DP's grand-daughter, so that she will be able to have a home of her own before she otherwise might have done, and some of it will go to her mother, so she and DGD can have a nice home for DGD to grow up in, instead of a rented flat on a busy main road with no outdoor space.
My DSS has his own house, courtesy of a trust fund from his GM, and will be a millionaire twice over when his mother dies, so he has no need of my money as well. He knows this, and is ok with it.
I don't know what more I can do really, but I do think life is a struggle for young people starting out.
