It depends on where you come from and what class as to whether you feel that way. For the UK and Australia the boomers were born into rationing. I know America experienced a boom after the war, but it took a lot longer to reach us. My parents, boomers, lived hand to mouth and that's what I grew up with, being grateful for a lot as things gradually got easier. I can't speak for Australian boomers as well, but I hear plenty of stories of surviving blistering summers without aircon. RVs, McMansions and aircon seem to be more of a recent phenomenon here.
I wonder if @riverflows and @mattclarke can weigh in on this. What was life like for your parents growing up?
Perhaps America led the way and the whole world following is the problem.
