Over simplification. But generally correct.

Unfortunately it misses out the huge % of low income earners who have fallen for properganda.

The right wing have spent decades convincing everyone that someone else is responsible for their low status. Without that the simple fact is those with less will always out number those with more. So it is essential to ensure those with less blame others for there lack.

This ensures that they are a divided vote.

This works everywhere if you can create enough enemies of different opposing types. But is much more effective in a fptp nation where minimal separation of ideals can allow control.
