Each generation is becoming more progressive because the shift towards conservatism is less about age and more about the accumulation of wealth. In the past as people got older they tended to accumulate wealth, but as the policies of the last few decades have been designed to increase inequality and redistribute more wealth to the already wealthy instead of to those with less that shift to conservatism has also been reduced. Unfortunately as governments have also been working towards redistributing power to the wealthy I’m not sure the shift in politics within the general population will help.
