The reason it isn't capitalism with extra steps is that the defining trait of capitalism vs socialism isn't the presence of markets (which long predate capitalism as a distinct concept), but rather who owns what and how that ownership is justified and structured. Now, arguably market socialism is more similar to capitalism than a planned economy is, but capitalism doesn't just mean an unplanned economy either (as those, again, are much more ancient than the term implies).

I don't think the meme implies any particular solution. To be honest, it doesn't really even imply a problem to be solved. To my eyes it just looks like it's just mocking a particular argument used to defend capitalism, without really communicating much beyond a distaste for that argument and presumably with capitalism in general.
