Hmmmmm I think we are poorer, but only a bit.
My dad was well paid and this meant my mum could stay at home, whereas, my DH is pretty well paid and I was made redundant on maternity leave with dc1. If I returned to work now, we would lose money paying for childcare, so I am compelled to stay at home. So fairly similar really, but we got here in different ways.
We could afford foreign holidays but we choose not to take them. We always holiday in the UK these days.
Our house is much, much smaller than my house growing up and a good bit smaller than my PILs. We also feel we couldn't afford another child (we have two), whereas my PILs and parents had three per family. But I grew up in Ireland and now live in the SE of England, so my parents' large house probably wouldn't be all that much more expensive than our small one.
I think we feel a bit poorer because we live in such an expensive part of the country, but that's our choice to a point, although, my husband's career would be non existent in Ireland. I don't work, so we really couldn't choose to up sticks and move there.
My dad eventually earnt a LOT of money. He didn't strike it lucky on the stick market or anything, he just had a job which paid a lot (well, a lot to us). But I know there was a time when we were very small that they were really poor too.
So, all in all, I think we're fairly similar. The main difference I think will be that our children might need more help finding a place to live when they grow up and also our pensions will be nothing like as generous as our parents'. So, I think the big differences are possibly yet to come.
