We're talking past each other. I don't call for pure anything either. However it's intellectually lazy the way capitalism is framed in this thread as the root of all evil. I want a social democracy driven by capitalism.
I'm pretty sure I understand your position. "Driven by capitalism" is the whole fukking problem. The reason we don't have social democracy is because of Capitalism. The reason that even a social democracy wouldn't prevent the world's environment from continuing to collapse is because of capitalism. Capitalism being the "driver" of society IS the problem.
Capitalism creates incentives unlike any other economic system to create productivity and innovation.
And I think that's boilerplate rhetoric and unjustified. Capitalism creates incentive to profit, it doesn't create incentive to be better. You claim it incentivizes "innovation", and yet capitalism is the #1 reason that we're still reliant on dinosaurs like fossil fuels, cars, industrial meat, etc. even though they're wrecking the basis of the ecosystem that supports us.
The very existence of "planned obsolescence", one of the most evil corporate terms out there, is purely the product of Capitalism. What kind of bullshyt innovation is that, where you purposely design products to fail or become unusable solely so you can sell more of them? Yet it's perfectly accepted in almost every industry and has become the norm even as it tears apart the planet's resources. How will your social democracy stop that?
There have been some important innovations made at corporate think tanks - often the same few spots are responsible, like Bell Labs or General Electric. But compared to their resources, government and university researchers have been FAR more productive in terms of real innovation. Nonprofit sectors spend much more of their energy actually trying to innovate, while the vast majority of capitalist corporations spend very little on real R&D other than figuring out what kinds of superficial exterior design and packaging and advertizing will get their product sold.
Also, your statement assumes that "productivity" is some sort of inherent good, even though it means that we're destroying people with overwork and destroying our resources with overproduction and overconsumption. Profit Motive and the basis of money creation via loans-at-interest have ensured that "productivity" must constantly increase no matter what it ruins. How is that a good thing, and what will you do to ever stop it?
Look at nations like Guatemala, where 70% of kids are malnourished even as the country has become a net exporter of beef, because regular people's farmland they need to survive is being taken over by rich beef ranchers who make far less food but can ship it overseas for far more profit. In capitalist terms, they've "increased productivity" by paradoxically becoming less productive in terms of calories produced. Because the only thing they actually want to increase is profit, not public good. The US turning into a social democracy wouldn't solve that.
Only tiny fractions of society experienced anything other than poverty and life expectancy greater than 35 years old prior 1750.
You're confusing correlation with causation. Most of the gains in life expectancy were downstream impacts of the increases in both scientific knowledge and human rights that appeared as a result of the Great Enlightment, and those didn't have jack shyt to do with capitalism. Let's list some of the greatest factors that led to that increase in life expectancy.
1) The widespread treatment of drinking water for public consumption
2) The building of reliable public sanitation systems for treating sewage
3) The institution of municipal garbage collection
4) The requirement of official public health standards and food inspection
5) The discovery of antibiotics
6) The development of sanitation in hospital settings, especially for childbirth and surgery
7) Improved surgical techniques
8) Improved scientific knowledge of proper nutrition
9) Universal public education
10) Banning of child labor
11) Control of mosquitoes
12) Development of vaccines
13) Improvements in air quality
Those innovations had very little to do with capitalism - in fact, in several instances (like child labor, horrible quality of factory-produced food, and bad air quality), the problems that needed to be solved were CAUSED by capitalism. I can't say for sure that capitalism has had zero positive impact on life expectancy, but the vast majority of the rise was clearly other factors. Communist USSR saw the same rises in life expectancy that the rest of the world did - in fact, as of 1965 the average life expectancy in USSR and USA were almost identical, and even as of 1988 they only differed by about a year. But Russian life expectancies actually DROPPED for a decade after the USSR ditched communism.
Cubans have a higher life expectancy than the USA even though America did everything they possible could to try to destoy the country's economy and access to resources - in fact, their life expectancy in Cuba is 7 years higher than the Latin American average.
And all that is just looking at the current state. What capitalists fail to acknowledge is that the current state is completely unsustainable because you're already destroying resources across the world at an unsustainable rate. It's like a squirrel bragging about how fat it got eating all its food in the first week of winter without the slightest concern for what's going to happen in the three months to follow now that nothing is left.
