I definitely can't think of any policies in china that would have potentially influenced this

Firstly, that's what policies are supposed to do. Solve these issues. How that is lost on people like you who want to elect politicians to solve problems for you is beyond me.
Secondly, how is the one-child policy relevant here?

4.2% of respondents who were unable to be assessed due to language barriers, cognitive disability, or physical disability.

Notably, this indicates that fewer USians are literate by the standards of the PRC that you opt to malign here.

huh, go figure. exactly my assertion that you can't hit 100%

Notably, the PRC's education efforts are evidently very successful. Just as I said.

So remind me again what was your point?

That communist projects generally provide good education for their people. Which is very evident at this point.

Dont get me wrong I admire some outcomes communist countries achieve just not at the cost

Notably, their achievements are much greater than that of this 'AOC' person who might not even exist.

Just as I admire some things capitalist countries have achieved

Like slavery and colonialism? Lol. Couldn't achieve much themselves but polish pig poop balls without colonialism.

Essentially both systems are fundamentally flawed

One of them boasts guaranteed housing, universal healthcare, elimination of illiteracy, massive increases of life expectancy, bringing about women's rights that we consider a given today, and so on, and so forth.
The other boasts colonial exploitation of most of the world, immiseration of billions, genocide of millions.
You opt to claim they are equally flawed and bad. And you also claim that a person who works to uphold the latter system is somehow good while having no achievements of note. You are being silly.

both systems are capable of massive outputs at the expense absolutely abhorrent treatment of people just in different ways

Guaranteed housing, universal healthcare, elimination of illiteracy, massive increases of life expectancy, emancipation of women, liberation of your colonies, etc. is not, contrary to what USians have been conditioned to believe, 'abhorrent'.
Going to note again that you are yet to actually say how the treatment of people by communist states is somehow bad.

And remember, I think both systems are shit

And you are being extremely silly. You even think that AOC - a high politician who works to uphold the obviously worse system - is somehow good, and that she should be defended.

I've looked into both. found both wanting on purely human decency grounds

If you find guaranteed housing, universal healthcare, etc. just as bad as slavery and near-slavery that your empire has been subjecting the rest of the world to, then you are just being an extremely silly branwashed Burgerlander.
Notably, you are literally in support of a politician who is involved in a genocide, and who is trying to maintain the worst version of one of the systems you claim to hate.

both are unstable

You keep making claims without being able to support them.

Communism because of its economic centralization is easily subverted and dismantled by dictators

'Planned economy (again, not synonymous with 'communism') is bad because it is dismantled by the governments' is a very silly argument that actually indicates that planned economy is good, as you find it bad when it is dismantled.
Also, you are one of those people who use the word 'dictator' but do not mean anything by the word other than 'the worst genocidal empire in the world told me to use the word against its designated enemies, so I will uncritically do so!'.
In any case, you are being very silly.
