I think I can understand those people coming from mostly Asian countries since their social status mobility upwards is similar to what we are experiencing in "Africa" - which is - our parents/grandparents worked hard either by themselves (self-employed) or for some not fair employers. And they have earned what they have built up unlike some people from a certain continent that went around stealing land and its resources, and annihilating the natives all for themselves and yet they are not satisfied that they still come to our so called 3rd world countries in the form of MNCs or some who come and marry the locals for temporary fun.
Countries like Canada and mostly those where the white caucasian forms the majority, are growing at a measly/not considerable pace in terms of GDP - under 2%. Whereas the non-white countries everywhere else are experiencing healthy growth rates of above 5% (
https://en.wikipedia.org/wiki/List_of_countries_by_real_GDP_growth_rate#/media/File:GDP_Growth_By_Country_2016.png) - this is partly to do with population growth as well. Point being that from now till 2100 at least, these so called 3rd world will be dragging the western countries and their multi-national companies out of mud. These are the places to be if you really want to be working and making some decent money unlike youtube vlogging. My country is a good example since in the last 7 years we have seen huge number of white folks coming to our country in search of better opportunities and they are very visible on the streets unlike before. Our embassy in London was unable to cope with the number of applicants that they had to fly out extra staff overnight as per BBC news - food for thought.
