Tax System + Marx = .....

This blog is a comment on Isa's blog about the people at the top getting all the benefits, while the workers at the bottom get none. In micro, we're just learning about the tax systems that have been put in place around the world, specifically in the United States.

Apparently, the principle of tax analysis is this : that "the burden of a tax is ultimately borne by individuals or households." The wage-earners and and laborers are the ones who must pay the tax. The burden of taxes that must be paid by a firm or an institution is actually shifted onto the consumers or workers.

I wonder what Marx would say about this. He'd probably fervently argue for the rise of the proletariat, but would that work as well as the system does today? Understandably, the tax system we currently have in place is extremely controversial and does not have the ability to satisfy everyone. But what can we replace this with? What else can work as (reasonably and comparably) well?

Any thoughts, Marx?
