The reason you will never hear a working class conservative complain about the billionaire class screwing them is because conservatives have always been the foot-soldiers of the billionaire class.
If not for conservatives, the normal people would be permitted to charge billionaires with crimes, force them to pay proper taxes and make them pay fair wages. If not for conservatives, the normal people would be able to unionize and to protest.
Without conservatives, workers would have mandatory sick time, mandatory time off, protections from wage theft and protections from improper dismissal.
Without conservatives, the normal people could address wealth inequality.
The boss cannot be defeated until his foot-soldiers are dead.
