When your material needs are satisfied then only ideological battles remain to be won.
And having lots of material stuff you have plenty to throw at the enemy.
It's already happening. People are willing to forego their material needs and harm the country and themselves to 'own' and defeat the other side.
The only hope is that the ideological wars become so scattered and around so many topics and centers of power that it's not 70m people vs. 70m people or that the ideological wars are slow that people realize that they come with a loss of quality of life and material wealth and rebalance towards the latter instead of pursuing the 'owning the other side' doctrine
