I don’t think that all 20-30 year olds have it easier, but neither do all 20-30 year olds have it harder.
No, nor do I. Many of them have chances that were denied to us, and it's never realistic to make direct comparisons between generations.
Until recently I thought that all generations had a hard time getting settled, but both of my children have been in the housing market over the past couple of years. My son has bought one, and my daughter is in the process of making offers. I put the cost of our first house into the calculator and it came up at £79500. The same house would cost £250k now. There is no comparison. Yes, there has been wage inflation, and I can't remember what we earned back then, but I do know that we only used my husband's salary in the mortgage calculations, as I was a student. He was 24, recently qualified and not earning a fortune, but we got a mortgage. We struggled when interest rates rocketed, but looking at what my children are going to have to pay, and how much both of them paid in rent whilst saving for a deposit (we didn't rent before buying) there really is no comparison.
I still live near where we bought the first house, and my children live in (separate) different areas, but roughly comparable for house prices. Of course the differentials differ depending on area, but even allowing for that it is much harder on the whole for most young people than it used to be.
My sister and I were talking about this yesterday and agreed that for anyone it is difficult to save when you are young, but that 'in our day' at least we could see the point because we knew that in a couple of years we would have a deposit for the house we wanted to (even though it was a small starter home). I married at 22, and most of my friends were that sort of age. I think the average age for a first time buyer is now 35, as it takes so long to save a deposit. Even 10 years ago things were easier.
