Manifesto of the Communist Party by Karl Marx and Frederick Engels. It's long, so I'll snip the relevant parts, you can search the phrases though to read the full sections:

...to centralise all instruments of production in the hands of the State...this cannot be effected except by means of despotic inroads on the rights of property...which appear economically insufficient and untenable, but which, in the course of the movement, outstrip themselves, necessitate further inroads upon the old social order...

And, here's the good part:

Nevertheless, in most advanced countries, the following will be pretty generally applicable.

1. Abolition of property in land and application of all rents of land to public purposes.

2. A heavy progressive or graduated income tax.
3. Abolition of all rights of inheritance.
4. Confiscation of the property of all emigrants and rebels.
5) Centralisation of credit in the hands of the state, by means of a national bank with State capital and an exclusive monopoly.
6) Centralisation of the means of communication and transport in the hands of the State.
7. Extension of factories and instruments of production owned by the State; the bringing into cultivation of waste-lands, and the improvement of the soil generally in accordance with a common plan.
8. Equal liability of all to work. Establishment of industrial armies, especially for agriculture.
9. Combination of agriculture with manufacturing industries; gradual abolition of all the distinction between town and country by a more equable distribution of the populace over the country.
10. Free education for all children in public schools. Abolition of children’s factory labour in its present form. Combination of education with industrial production, &c, &c.

And I could have gone harder, as some of these are half-complete, or more. But, yeah, Taxes, central banking, consolidation of transport/communication, unions, public education. All things Marx and Engels themselves advocated for.

But wait, there's more!

Demands of the Communist Party in Germany
“Workers of all countries, unite!”

1. The whole of Germany shall be declared a single and indivisible republic.

No states' rights.

3. Representatives of the people shall receive payment so that workers, too, shall be able to become members of the German parliament.

Well, that went well. To be fair, our current system in this respect, is not what Marx was talking about. It is funny how much the modern Marxists hate the more everyman politicians, though.

4. Universal arming of the people. In future the armies shall be simultaneously labour armies, so that the troops shall not, as formerly, merely consume, but shall produce more than is necessary for their upkeep. This will moreover be conducive to the organisation of labour.

Alright, fine. Based Marx on this one.

8. Mortgages on peasant lands shall be declared the property of the state. Interest on such mortgages shall be paid by the peasants to the state.

Power to the people...State?

And, here's the good one:

10. A state bank, whose paper issues are legal tender, shall replace all private banks. This measure will make it possible to regulate the credit system in the interest of the people as a whole, and will thus undermine the dominion of the big financial magnates. Further, by gradually substituting paper money for gold and silver coin, the universal means of exchange (that indispensable prerequisite of bourgeois trade and commerce) will be cheapened, and gold and silver will be set free for use in foreign trade. Finally, this measure is necessary in order to bind the interests of the conservative bourgeoisie to the Government.

They specifically wanted to use paper money - presumably fiat - explicitly for the purpose of making it worthless, while also using the actual wealth for foreign trade. Hmm, sounds familiar.

11. All the means of transport, railways, canals, steamships, roads, the posts etc. shall be taken over by the state. They shall become the property of the state and shall be placed free at the disposal of the impecunious classes.

14. The right of inheritance to be curtailed.

15. The introduction of steeply graduated taxes, and the abolition of taxes on articles of consumption.

17. Universal and free education of the people.

The Committee
Karl Marx, Karl Schapper, H. Bauer, F. Engels, J. Moll, W. Wolff

And I either haven't read these, or haven't in years, so can't vouch for the exact contents, but here's two search results that showed up: Mises Institute talking about it, and MostlyEconimics blog, whoever that is.
