I find some of these remarks very mean spirited. I think life is much more difficult for younger people than it was forty or so years ago. There is a massive housing shortage, incredibly high rents, in many cases stagnant wages, and many people in their thirties and forties are really struggling, particularly if they have children.
It is difficult to compare the experiences of people born in the 30s/40s/50s with those born later. There were fewer foreign holidays then, no mobile phones or computers, etc. etc., much less access to credit and and much less sophisticated marketing of products.
We found it quite a struggle then but I would rather be back in the position we were in as a young married couple in the 1970's than to try and manage today. Even though my husband was a poorly paid student nurse and I took a couple of years off work when I had my first child, we were able to eat reasonably well and properly heat our rented hospital house (though we didn't have a telephone). I don't think that would be possible today on one low wage.
