Since around the 1950s (I think), we experimented with consumerism in earnest. Labour saving devices for the home. Cars. Fashion. A diverse range of food and beauty products. And, I'm sure, lots of other things. Since then, consumerism has snowballed. Now we're concerned with which model of iPhone to own. People come home from shopping malls with armfuls of bags. If they can't afford the items they want to buy, they charge it to a credit card. Debt has become an issue for some.
Homes are stuffed full of the latest products. Many are not recyclable. Landfill, here they come. The planet is groaning under the weight of so much stuff.
What is "enough"? When will we have "enough"? People don't seem to be able to recognise what "enough" is any more — and until that gets solved, none of the other problems can really be addressed. Overconsumption, overwork, the constant reaching for more: they're all downstream of not having a working definition of "enough" in the first place. It's not one problem among many. It's the problem underneath the others.
If we had culture instead of consumption - which is everybody for himself, not relating to people - we would not have climate change ~ Vivienne Westwood
That's a harder question than it sounds, because "enough" isn't a fixed number — it moves with what you compare yourself to, what you're anxious about, what you've been sold. Recognising it seems to take active practice, not just willpower.
