You cannot generalise. I worked hard before and after I had my children. I received 18 weeks maternity allowance for first child, and family allowance when my 2nd child was born. Those were the only benefits we received.
the difference is that a generation ago, most families had only one earner. Nowadays, that's far less true, making the need to two earners more necessary (for things we all compete for, say property, you need two earners to keep up). So, while benefits may have been more meagre (however, see below), you didn't need two earners like you do now.
As I said before, if I started moaning about younger people on benefits with all the latest gadgets, smoking and drinking, then I know I would be called an uncaring person, and told that they deserve it.
the young spend more money on gadgets because that is what they can realistically afford. While they get a pittance in state help now, the older generation got right to buy on a grand scale, university tuition and a sane property scene. They got help on a much bigger scale in the things that REALLY matter. most young people, I would guess, see it as literally impossible for them to buy a house, so why bother saving? if the choice is saving for 300 years for a house or getting that iphone now, it's a pretty clear choice.
