You're acting as if capitalists treat their workers well under the current system when the opposite has occurred. Nearly $50 trillion was stolen from workers [1] by the capitalists owners in the US. Income inequality is literally at worse levels than just prior to the French Revolution.
The first politician to offer $1 trillion in federal assistance to middle/lower classes (free healthcare, free university/vocational training, public housing, public jobs) will absolutely control the electorate at both sides of the aisles.
Remember that redistribution of wealth are very popular American activities. It swings both ways.
