I think there is a significantly deeper problem in your country than mine with racism. Although Britain participated in the slave trade most of our economic leap forwards came at the expense of our existing agricultural workers. There was some slavery here but not to the extent and scale that happened in the US.
In your country, class and race are a pretty good indicator of the same thing. Over here, that's not quite true. The vast majority of immigrants to this country arrived after the 1940s and many of those families became quickly upwardly mobile.
In your country, socialism is seen by the white middle class as a way of giving money to lazy black people. They ignore many of the disadvantages that come with lacking generational wealth/poor schooling/expensive health care - all those things. I would imagine they see stealing as a race tax. That's why the Taft-Hartley Act got passed despite Truman's best efforts - it was a conflation of race and socialism. Until the US is able to break out of that mindset and build an economy that allows some rebalancing of opportunity for poor people - you're going to be stuck.
I think the US was founded on racism. It took it's founding document "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the Pursuit of Happiness" - and then refused to apply that to people of a different race.
In some instances that discrimination is still true today - and that's what America has to reckon with before it can progress to being more of a utopia. I do believe racism exists, I do want it to be stopped, I don't believe identity politics is the answer. Even not agreeing with identity politics is currently seen to be racist - and that's a problem. :o)
