Its a massive issue and will only get worse and worse with the way modern society funnels money from the poorest to the wealthiest
Maybe you know more about economics than I. But I can't reconcile that statement.
Start with China where almost everything has been made for the last 30 years.
Between 1990 and 2015, 746 Million ( 3/4 Billion) people in China were lifted above the poverty line on the back of manufacturing and exports to these so called wealthy countries. ( Source Unicef) The income and cost of labour in China have moved from the east coast, slowly to the western provinces. And now they are living a life out of Poverty. And companies are looking elsewhere for labour. Ask those people if they are poorer because of the richer countries buying goods they make. It has has helped so many people, the closing in the gap between China and US wealth has been called the Great Chinese Economic Miracle. All funded by Western money pouring into China in exchange for goods and the labour to make them.
So... with the increase in labour rates ( income) a lot of production in the last 10 or 15 years has moved to Vietnam. The Poverty rate there has gone from 78% in 2008 to just 23% in 2020. I am sure they are bitching - NOT!
Next? Bangladesh where all your Socks and T Shirts are made now. 50% poverty in 2000, down to 21% in 2019. It has saved millions of lives and allowed women to earn family income and be empowered. Lets listen for them asking to go back to the good old days before richer countries started buying manufactured goods there ..... crickets.
Cambodia, India, Laos, Burma, etc is the same story. Just like Japan, Taiwan, Singapore, South Korea 30 - 50 years ago. Probably the same for Mexico where most US cars are made now.
So maybe I don't get it. Across those countries, probably 1 - 1.5 Billion people have risen above the poverty line with increased wealth. I'd be amazed if they agree they are worse off.
Sure they don't drive nice cars or use uber eats, but they do have increased wealth, income and lifestyle because of the West buying goods.
I'm not saying your statement is wrong, I am saying that it simply doesn't add up to me. I'm no economist for sure. Can you please explain on what basis is the money funnel going the other way from them to us as you say?
