Fix Africa, fix South America, fix SouthEast Asia! Outlaw wars! If migration becomes solely a matter of choice and not out of desperation or due to displacement, then the present feeling of intolerance will melt away.
It is naive to think discrimination or racism is solely from one singular race to another. It isn’t. Everyone has the tendency to discriminate. There isn’t a huge degree of intolerance towards folk on holiday as the host countries expect to benefit from their visit.
If Africa can sort itself out: eliminate corruption, drop archaic practices, educate all, mechanise agriculture, step up! Making it a continent nobody wants to leave, with only a few exiting for short periods to holiday around the world, the dynamics will change immeasurably. At present, sending people to Africa (e.g. Rwanda) is seen as an effective deterrent! That speaks volumes!
Same logic applies to the frequency mass migration from South & Central American countries to the US. If those countries can be transformed to safe, prosperous havens that nobody wants to leave, the value of their citizens will rise globally and so will their treatment when in the US, if it is clear they are only there by choice and not for survival.
There is nothing magical about this. We all know it is the only fix and it is very doable, but perhaps we are reluctant to improve those parts of the world? Perhaps we are reluctant to end wars? end displacement? Heaven knows why???!!!
Knowledge can improve the world we live in
