If you agree with Marx's view that the lumpenproletariat lacks revolutionary potential are you worried about it expanding? Because its certainly looking like thats the way most developed economies are heading.
As for your question of civil servants I think it depends for the most part on the kind of civil servant you mean. Certainly many of them are involved in the productive processes, managing public resources, enforcing safety standards. Certainly, your claim that they are essentially paid by the capitalist class to manage things is correct, so I have to wonder what appreciable difference there is between a civil servant working on social security and an accountant working in corporate payroll.
Apologies for any problems with this post, I am on a cell phone.
