If you can't wrap your mind behind the idea that new uses for human labor will develop as it is freed up in the future due to technological advancements then I suggest you should not hurl this statement around so freely.
Horses and animals were once the muscle that drove humanities industry.
It is you who sound like a luddite.
Why must humans be made animals to be worked until exhaustion past their prime when automation can do the work freeing up one to find their own ideas of work?
This "work ethic" you think is immutable is a victorian era protestant farce steeped in centuries old racism and imperialism.
Ever thought of how actually stupid this old protestant imperative is getting to get up at the crack of dawn and busting your butt all day actually sounds to people in areas near the equator?
So have the rest of the world held under the thumb of the British empire. This is where it comes from.
It's a poorly thought out northern European
tradition to bring "civilization" to "savages".
We live in barbaric times still, we literally just climbed out of serfdom a few hundred years ago.
Capitalism is not the end game. It is the ass end of unsustainable (wage) slavery when you look at it from the renaissance to the founding of modern democracy in Europe and here to now.
Everything from not being a literal slave to your landlord to 8 hour work days were hard won from the elites (the corporations now) and religion -just in the past 100 to 200 years.
We have a lot of old baggage to get over. How arrogant to think what we have will (or can) be sustainable.
The only legacy we will leave is a buncha trash and toxic wastes for future generations, who would even want to pass this mess on to future generations? They would curse our names for eternity.
I don't have all the answers to the future.
I am just saying it is good to think about doing better in the long run.
We all know this shit is busted. Regardless of how we disagree on who or what pet issue is to blame.
