What is some good left leaning anime?

That one animu about porn liberation

Besides that, animu is shit. Western cartoons master race.

Which western cartoons are any good?

Family Guy. It actually has subtle far left undertones to it.

If you're interested in Gundam showing capitalism to be fucked up, the original universe as a whole does actually have a bit of that with the energy production industry and weapons development industries both heavily affecting the political environment and causing multiple conflicts through profits. Of course, it's still an anime so it does it clunkily and rarely but it's something.

Venture Bros
Metalocalypse
Rick and Morty
Those are the top three that come to mind at least.

Ignore this faggot

The new Gundam Unicorn asserts that the reason for the Earth Sphere oppressing the colonies is because they know that the Earth is a dump and as soon as the colonies achieve economic independence they'll leave the Feddies in the dust.

But of course they never criticize the system itself, just the corrupt officials that run it, and frequently pull the "both sides are just as bad!" shtick.

anime is inherently bourgeoisie and fascist propaganda
