i'd do some intellectual property reform.
some banking reform - more local / peer group/long term lending requirements, less fickle international finance. (and less fucking mortgage bubbles!)
some small business support / starter initiatives - link that in with how banks work.

i'd consider lobbying for some government sposored work to generate open source plans and enable production processes for useful tools - Okay that isn't going to happen , , ,

but it's not all or nothing, but you can do things to help some more workers control and access more of their tooling even if its not outright ownership of the end to end production process.

(By the way i'm basically arguing for a more "free" market in the ecnomic sense (easy access for a large number of small scale producers). . . which is exactly not what large-scale capitalists want.
They want a market "free" from any thing that might regulate their attempts to secure economic power and their abiity to use it to generate supernormal prices/profits.)

Progress doesnt happen in 4-5 year political cycles thats a hard one to improve without an electorate capable (any maybe secure enough) to thing about the longer term. Odd that it was extreme econmic and political uncertainty that brought out the likes of FDR and other post-war that people were most willing to think long term when it came to their governemnts - I guess it brought out all sorts of "crazies".

The big one in terms of bloodshed is land reform - and it has been done in a few places - sort of post-colonial type situations - but granted it does ususally have blooodshed. It's a personal judgment what degree is "excessive bloodshed".
