The problem is not people making money with dropshipping. The problem is that these countries and their people do nothing to fight children exploitation and bad work conditions. You didn't mention any big companies like Amazon, Ebay, H&M, the big fashion firms... they all exploit the poorer eastern countries to produce their products, which we happily buy and nobody complains about it. Even if those big companies handle the products and keep them in stock, does it make it less disgusting when you think about the exploited children?

I have the solution to fight this problem: make eastern people realise that their work is worth much more.
