We have a democracy in that we choose between two or more candidates to hold each political office. We've also steadily been developing a feudal society, having already stripped the poor of a list of basic civil and human rights.
Mobilize who, and for what? For the past 20 years, liberals have maintained that our deregulated capitalism is so successful that everyone is able to work, there are jobs for all, therefore no need for poverty relief. And much of the country knows they're wrong.
Liberals call for protecting the advantages of the middle class, recently revised to "working class." A revolution to maintain the status quo? Well, this isn't the first time that the richest few gained a dangerous degree of control over our politics and policies, to the harm of the country. Each time in the past, the "masses" ultimately came together to successfully push back -- poor and middle class, workers and the jobless, for the common good. That can't happen this time. Years of work have gone into pitting us against each other by class and race. Now what?
What US history shows is that it's impossible to save/rebuild the middle class without legitimately addressing poverty. Many understood that the Obama years represented our last chance to do this. It was worth a try, but didn't work.
