It’s alive and well. Contemporary liberalism is based around white guilt even more than class warfare. The white working class has proved unreliable. Hence it is now slimed as “white trash”, and the left as aligned with a different proletariat.
Agree—its alive and well. If anything, as whites give up more power, it will get stronger—as will the demand for mitigation (like reparations, automonomous regions for minorities, increased immigration, etc).
