Well, woudn’t be the first time words get new meaning due to events in history.

In nordic countries using taxation to limit gap between rich and poor, keeping government control of vital resources, free government sponsored healthcare, handing social welfare to poor and disabled, etc. is considered socialism.

Right wing politics is the opposite. They want to privatise everything, leave the poor and the disabled to charity organisations that work on donations from people who care, don’t think the rich should be taxed for being rich. Basically minimising government ownership and control of societys money flow to establish truly free market.
