I'm not sure how to take this. Does it imply that you don't believe the US political system will be able to deal with income inequalities, and that it is doomed to fall apart? Cause otherwise, the only other outcome is that the system changes itself from within over time and quality of life remains high for its citizen and the country stays prosperous and able to sustain itself. Which would mean someone will eventually work with the system to change it, otherwise it's doomed to fail.
