Incorrect, the barrier to entry for the government is much lower in China than say, the US or 'democratic' states. China doesn't arbitrarily kill citizens, their police aren't even armed. What does happen is they're arrested and sentenced to education and reform, which does include how to redress complaints. All public workers are unionized in China, and there is no barrier nor suppression of private unions in the private sector.
The state in China objectively isn't the capitalist class they don't own capital. With public ownership of the means of production (in any public sector industry) it is by definition socialist. By every definition socialist.
Your confusion on this matter comes from the fact western sources do not publish how the Chinese government works or how easy it is to become a member and participate. The state equals the people, anyone can join he government and take on the boring admin work, there are checks at every level to reduce corruption and no one person ever has absolute power. Technically "the evil dictator Xi Jinping" could be ousted with a single vote, or multiple lower regional votes. The same is true for all positions. Appointments are democratically placed, so corruption is minimal. 400 million people would have to be unified and absolutely corrupt for the state to be corrupt. And that's really hard to do. The US can't even get 100 million people to agree to any single thing.
The US has income based repayment plans for all federally guaranteed loans. By removing or changing the limits in the formula, which is likely what Trump did, people that were paying $50/mo might have to pay market rates for their repayment which is unaffordable to pretty much everyone.
With ibr your interest tends to not increase despite having a much longer repayment time, allowing you to, you know, live and pay your student loans instead of having to choose in most cases.
