There MIGHT be enough PEOPLE to make the capitalists hurt provided they're motivated, but I'm not sure there's enough political class Democrats to do so. At least not enough of the Democratic leadership to do so.

One thing to remember is that the Dems are a bourgeois political party that are in lockstep in support of the capitalist system. Which puts them in a weird position RE: strikes and the class struggle. Regarding the class struggle, the BEST Dems want to be on BOTH sides. A large minority (majority?) of the leadership who call themselves Democrats, do everything in their power to support the capitalists OVER the will of the people. That's why you see situation like the political class taking positions on issues at total odds with what the people support on ISSUES. The recent marijuana dust up is just the latest example.

At one point it could be argued that it was possible to be on both sides of the class struggle. As a Marxist, I never thought so, but some could argue that at times in the past when the economy boomed. Not so much anymore. The crux comes when capitalism falls into crisis as it did in '07/'08. Then the situation gets pushed by the financial elites to the point where they want it ALL. ALL of your money, ALL of your labor on THEIR terms, and what's worse, they want ALL OF YOUR LOYALTY to a system that enslaves you.

In short, I don't see a large majority of the Democratic leadership taking the side of the people against the system. Ergo, the people are on their own in this fight.
