We just need to make few nations rich and most part just working for them so we can provide for UK USA canada people sercurity and good food and good life again without even people working in there like it use to be this will keep safe again those.
What you are implying is indirectly happening, it is most of the developed countries that are milking the resources of undeveloped countries, they will take raw materials and develop it in their countries then become richer. The effect is that as these poor countries are getting poorer their citizens will be looking for a better life and be flooding developed countries like UK, USA and Canada. Check the rate of migrants from many countries that are looking for ways to enter these developed economies, it is on the increase. But if every country is developed like UK, USA, Canada and China, everybody will be happy in their country and crime rates will reduce in the countries that I mentioned.
