In my primary school, in 1952, there were three intakes of children in September, January and Easter, and they were fed from infants into classes 1a, 1b, 1c and 1d and so on, right through to juniors. I just checked out the infant class I was in and there were 48 of us! The a, b and c classes all had 40 children and the d class the remainder.
My dad worked 6 days a week, and mum looked after the four of us and the home. We had no TV, just a crackly radio, books, board games, about five or six presents at Christmas and for birthdays and we had no understanding of consumerism.
If those criticisers of boomers compare how they generally (not all, by any means) spend and waste belongings and food with the boomer generation, they might give us credit for not being the generation that eats up resources and expects more than we can afford.
