Nothing. I think a global economy is great. But people are going to have to accept that their "standard of living" is going to be different on a planet with 4.5 million humans (1980) and 8 billion humans (now). As natural resources dwindle, technology replaces the need for human labour and space is ever-shrinking, it's absurd to expect that one will be able to command ever-expanding amenities.
Not to mention, back in those days people like to hark to, those average people some think were so well of weren't awash in tech and gadgets, didn't travel internationally, most didn't go to uni, dining out and takeaway were very rare treats, and even things like eyeglasses were precious purchases that were carefully handled, repaired if broken and not taken for granted.
Expensive sports and extra curricular activities were not the norm for most families -- my parents WORKED from age 12 or 13 to augment their families' income, after school and on weekends. In the late 70s and 80s, I worked part-time from the age of 14, doing child sitting, cleaning and yard work, then office work after age 16. We got new clothing at Christmas and on birthdays, and that was that.
I remember asking my mom as an adult why she never let us get an ice cream from the neighbourhood vendor, it was a few pence, and she said "we simply couldn't afford it." A bag of crisps and a couple of cokes was a once-a-month treat.
Yes they could buy a house three tiny bedrooms, one bath in their late 20s/early 30s but they didn't do a heck of a lot else. And they were perfectly normal and not deprived; our entire extended friends and family circle was exactly the same.
To say families are "suffering" because they can't afford holidays, takeaway food, recreational shopping, cleaners and costly activities for kids is absurd.
