That raises a whole host of other issues. They're $200, because they don't have to pay their employees or provide a safe environment, the Government is subsidizing the manufacture or other unsavoury reasons. You can make things really cheap if you don't care about your staff.
Complete speculation, you’ve downed too much propaganda.
Manufacturing is cheaper in cheaper countries because of less taxes, inflation, bureaucracy, and a dozen other factors that aren’t negative socialist bullshit. Their workers get by just fine with the wages they’re paid.
The Chinese government subsidising the manufacture of wheelchairs doesn't sound as nefarious as you're making out. I would be proud if my government did the same thing.
