I don't think it's significantly worse now. I think expectations have changed.
I'm in my 40s and was never able to get on the housing ladder due to being single. All of my friends who did were in couples and virtually all of them had parental help with a deposit.
I recently watched 'The family' on Youtube, the 1970s first 'reality' show where they were bemoaning how it was impossible to get a council house as a young working family so the daughter, husband and baby were living with her parents.
I've also recently watched early 80s Only fools and horses talking about cuts to social services, failing NHS, crap YTS schemes meaning Rodney has to work with Del Boy, can't get a proper job and them both having to share a flat with Grandad.
I think it also depends where you live. I'm in the South-West I know someone with 6 kids, the eldest 21 who works full-time in a supermarket and has done for years - rents a flat with his GF who works full-time in Costa. A 20 year old who's had three full time jobs in the last couple of years as didn't like the 1st two, and an 18 year old who works part-time in a chain restaurant while finishing her college course. None of them have been out of work since being old enough to work and definitely didn't have to apply for hundreds of jobs.
I work with lots of people in their late 20s, all making decent enough money. Only one still lives at home, the rest are in flat shares with partners or friends. They don't report having had extended periods not being able to find a job or making hundreds of applications either.
The only young people I know who aren't working are signed off sick.
