Consuming less is an act of rebellion. Consuming the minimum is revolutionary.
In Marx's view, 150 years ago, the economic contribution of working people was their labour. Sometimes called "the labour theory of value".
Marx was not prescient. He could not have envisaged was how capitalism would define (or redefine) the contribution of working people in terms of the goods and services they consume. It is out consumption that drives demand, which drives profit. And profit is the raison d'etre of capitalism.
Our desire to consume is ignited and fanned by constant and intense propaganda (aka advertising). We have never been exposed to more advertising than right now.
Capitalists see labour as an overhead, not a contribution. We are supposed to "work hard" because that keeps overheads low and maximises profit for the capitalists. Lets face it, working hard has no benefits to us since they don't pay us extra for working hard and it leaves us with no energy for, e.g., our families. The exception is those who have been shouldered into the so-called "gig economy" (formerly known as "piece work" an unfair and outdated system that unions managed to virtually eliminate 100 years ago).
Since consuming is our great contribution to society, it makes sense that products have a limited lifespan and have to be replaced often. People with money will tell you it's better to buy quality because it lasts. But if you don't have money you don't have the choice. The poor are stuck with the shoddy ersatz knockoffs that breaks as soon as you get them home. Low quality goods drive ongoing consumption.
There is no more working class or middle class. Everyone is "consumer class" now. And we are now further from the levers of power than we have been since our ancestors were serfs in a feudal state. The main parties in Britain all have the same economic view, the only view that is taught in universities. It literally does not matter who we vote for in the UK anymore.
And yet over-consumption and planned obsolescence seem likely to make the earth unfit for human habitation in our lifetimes.
Consuming less is an act of rebellion. Consuming the minimum is revolutionary.
And if you consume less, you don't need to work hard. You can put energy into what matters to you.
So... Grow your own and make your own. Do without. Recycle. Reuse. Buy second hand.
