I do not agree that 'elevating' someone back to a certain class will solve racism, for example.

Such an idea is an overly simplistic 'solution' to ingrained, structural issues and modes of thinking.

They must be tackled at the true root of such a problem, things like white supremacy which are not inherently to do with 'class' but a political ideology and way of seeing the world far beyond the limits of 'class' could ever hope to understand.
