The comment it is in reply to says:

At all levels of government we’re (worldwide) making due with less while these fucking parasites grow.

So Yogthos provides a counterpoint where a government is investing in the lower rungs of the society instead of squeezing them. If you want to dispute the mentioned facts it's one thing but the comment is still relevant and not out-of-nowhere China shilling.

This thread is about a dude in Ireland. It has nothing to do with China.

“why are we talking about the communist party of china under an article about how the bourgeoisie continues to accumulate wealth to the detriment of the proletariat?”

The thing is that the comment rings true about the other AES countries also. OP (of the thread, not the post) has identified a problem, and the commies are suggesting a solution to the problem, with statistics that prove it to be viable. You're dismissing the solution as off-topic, but it's very relevant. The thread is directly relevant to the article, and the reply is directly relevant to the thread.

Say what you want about the west, but China isn’t what the world should be either.

But it is. In lieu of something better, we should all be like China.
