You are an idiot. We are comparing Britain, Spain, portugal, French etc as Colonial powers as all of them at one time were great powers with colonies allover the world. I did not say Britain colonised Europe.
Spain colonised and settled much of Latin America and look at them from Mexico to Argentina, they are all 3rd world poor trash countries.
Portuguese colonised Brazil and Congo and settled in brazil, Look at them both countries are the poorest countries respectively in their continent.
French colonised many parts of western and central africa but didnot settled them, so it is understandable that those ex french ex colonies are poor.
Britain on the other hand, colonised and settled USA, Canada, Australia and New Zealand and turned them into the world's greatest and best countries.
If HDI has any meaning then why oh why Iceland no 1 in HDI is a bankrupt poor trash country now?
