Absolutely alleviate for all. However it doesnt get away from the fact that its a fact that the majority of people at the back, both in this video and in real life happen to be black. Well, they dont just 'happen' to be black, do they? Many people believe the reason nothing's been done about it is purely because they are black, so society has ignored them for so long.
Also most are immigrants. The history of immigrants over modern history is similar whether from other nations or just from agricultural labour to town working class. The relevance of ethnicity is irrelevant of each outcome.
People move to work and the people wanting the workers want them at the cheapest rate as one would a machine, stored and maintained at the cheapest until their usefulness is complete. As the competition for jobs and resources becomes acute then groups of identities appear encouraged by the powers that be and the groups become rats at war with each other.
This is compounded by closing or sending manufacturing overseas and off shoring jobs, it makes even less descent employment and scarcer resources therefore exciting the identity rats.
Its only when the rats realise that they are all the same and are being played do they move forward.
People have known this for ever but are encouraged to look at their own identity and believe that is the problem. We know some solutions that work, take the victorian philanthropists with model factories and villages.
There are other examples from history, what about the gorbals in Glasgow, one of the worst deprived and crime ridden places on earth. Slum clearing and social resources changed the situation (not completely).
Identity politics is part of the divide and rule that keeps us under control.
Move forward to rid the causes of want and inequality and everything else will come.
