Its not meant to make things better... Communists (hiding behind the name: Socialism) cannot succeed in a prosperous country. Prosperity must be torn down so the social order can be rebuilt
Yes, the idea of C-P is that particularly by overstressing the entitlement system and intensive abuse of legal process to that end, the machinery of the State can be destroyed, and ultimately replaced by a far-Left system of social and economic organization.
It's a flawed strategy for two major reasons.
First, it depends on a competent far-Left system being ready to take over and quickly implement itself, and the world has yet to see a competent far-Left system. Failure to immediately deliver the goods will quickly render the Commies (Or whatever) as unpopular, and subject to the same forces of destruction, as the government/economy they so recently brought down, with a reactionary Right-wing oligarchy that can restore basic services and meet needs being the more likely outcome. This is not the Russia of 1917 or the France of 1789 with a numerically-huge, disaffected, and politically-penetrated military waiting to assist a revolution, most of the rank and file of any militias would actually be taking political stances more like the
Freikorps of 1919 Germany the
Garde Nationale of 1789 France.
Second, it is all posited on a non-adaptive, rigid reaction to the worsening situation by the government in power, which is an extremely stupid assumption to make when dealing with any institution run by live humans instead of some straw man or computer game single-player-opponent algorithm. Despite all the bad-mouthing from both sides about gridlock etc. in our system of government, it's really pretty damned adaptive to impending challenges, it's just not real good on the 10+ year-out horizon stuff.
Cloward and Piven were Leftist ideologue true believers academic dipshits, with a fundamentally stupid idea which has been turned into a bogeyman by the Right. It can do a lot of damage, but it's not nearly as dangerous in the real world as everyone wants to paint it.
