Democratic leaders need to stop being afraid of talking about class issues that aren't just the usual evils of the billionaire class. For example if you can't afford to buy the product sold by the company you spend 5 days a week working for, you're being exploited, and etc.
There is a neo-bourgeoisie, and Democrats need to ease up on catering to it so often with messaging about education and whatnot. It obviously annoys working class people. Some folks don't want to work in a cube all day.
