You can quote as much Wiki as you like but your highlighted is a perception and it is quite wrong.
I have visited enough factories in China to know first hand that working conditions in most of those I have visited are no better than for Battery Hens.
The endless repetition of work practice, the mandatory 10 minute break per hour spent slumped at a bench "resting" , the regimented Dormitory Life before the mass release back to Family in the Provinces during Chinese New Year. I'll add that the workforce was 99% female but they earned enough to send back to their families to supplement their meagre existence.
I can understand why the current Chinese Leadership is adopting Capitalist methods to redress the crass stupidity under the previous Maoist Regime.
But I have also enjoyed every available luxury in Shanghai and Beijing that the previously referred to Battery Hens, and I don't mean that as an insult, but a reality, have absolutely no idea exists because the media/Internet is controlled to exclude.
My game at the time was that I owned a small electronics design company (capitalist small c) with a Singaporian Partner responsible for the Manufacture. On another occasion I visited what was called a Factory in Bangalore India in a crumbling 3 Storey Building. In a room around a large desk this time exclusively men with tweezers were placing components on a circuit board. I politely thanked them for their invitation but my host insisted I visit another business in the same Building. Reluctantly but politely I agreed, to get entry I first had to put on protective overalls to enter a clean room. I obviously thought they were taking the piss but on the other side I was talking with Indian Neuclear and Space Scientists who had tired or living in Israel but rather than be cut adrift the Israeli Government had set them up do do I don't know to this day Gods knows what research.
Overall what I'm saying is be cautious of what you read but learn from what you actually see and experience yourself.
What were you doing in all these factories in China to begin with? I presume it relates back to western capitalists who are paying for goods to be manufactured in these factories and as long as their profits are there they have little concern? Ethically did the businesses you work for do anything to move production to maybe say the UK were there are better working conditions? Or were the profits more important than the terrible conditions witnessed?
To my surprise it seems that in China they get more annual leave on average than in USA. In USA there isn't any legal entitlement to annual leave which is crazy as the biggest economy in the world. In China the healthcare is much better for the average person too and I presume higher education is significantly cheaper too.
Of course there'll always be anecdotal evidence but when the richest country in the world doesn't even have a law for annual leave entitlement (after 12 out of 16 years of "left wing" democrat rule) and much worse public health care amongst other things - I don't think we are in a position to look down on China.
My first paragraph I typed before reading about your electronics design company so it wasn't meant to be personal as many/most businesses nowadays seem to use Chinese manufacturing so you aren't alone. So is it not very much similar to some of the climate change stuff in a way? We aim for "net zero" by simply moving the production to other countries which doesn't actually help the planet besides UK saying "look we are greener" all while the same time the largest companies have just exported their carbon footprint outside the uk. And the same with "workers rights", all well and good saying or implying its better here but then the capitalist just goes and exports the work to other countries like China because profit always comes first.
And so I still believe the contradictions between Transnational Companies and Sovereign States will see the demise of capitalism as the corporations don't have any loyalty, their loyalty is to share holders and... delivering profits. Look at the way Musk talks about the UK and does the UK do anything? Nope nothing. He's basically showing that he's immune to any sanctions because he's bigger than us now. And so we continue with our regulated economies where we basically just bow down to the corporations because we can't "spook the markets" as the corporations power grows bigger than the governments.
Capitalism is a ticking time bomb. For all it's criticism Chinese people are better off than they were 10, 20, 30, 40 years ago and that trend is continuing. Western people are worse off than they were 10, 20, 30 years ago and that trend will continue to.
What's the solution? Sanctions and war against China? Yet another war against a socialist/communist country? But then the corporations who are growing more powerful than the states depends on China for their profits. So if you go to war with China what impact will that have for the global markets. Will the many businesses invested in China support that? How many businesses would go bust if we did that.
And so there are the great contradictions between State and Corporation. Capitalism isn't sustainable.
Some may ask "name me a succesful socialist country?"
I'd reply "name me one which the United States of America hasn't used economic warfare, sanctions, supporting proxies/rebels/oppositions, funding coups or just plain old invading." No dictator is too much for the USA as long as that dictator is happy to be a puppet.
