I do have to agree with you there. Though too much urban migration does come with its own problems. Chief among them that I observe is that it severely depressed wages and lack of work. China is moving through its own sort of gilded age right now with rapid technological advancement and extreme inequality.

For a purportedly socialist country, China lacks a lot of state infrastructure that comes along with that. The USSR guaranteed work and bread, at a minimum (mostly), but in China, a curious sight emerged which I observed in some of the poorer neighbourhoods of Hangzhou: old people pushing around carts of discarded cardboard boxes and tin cans. They weren’t employed as cleaning workers. They were collecting these to sell for their recycling value. And even though the Westerner might laugh at the notion of making a living collecting literal garbage for pennies, it only takes fourteen pennies to make a yuan and ¥5 will buy a bowl of rice, fending off starvation for another twelve hours. Now, homeless people collecting rubbish to sell for scrap does also happen in the US, but the US at least doesn’t claim to be a socialist country.

China has no functional social safety net, government assistance is minimal, and workers are exploited by a ruling class of wealthy elites with minimal interference from the state, in a shockingly similar way to capitalist countries. You cannot even form a real trade union in China, because all big companies are already “unionised” with workers represented by farcically corrupt organisations which work in tandem with the capitalist bosses.

I will give one more example: Coco is a nationwide chain of beverage stalls which sell tea, coffee, and juice drinks. I walked past a location in Shenzhen which was advertising that they were hiring. Their offer of pay: ¥200 a day, for a 10-hour shift, six days a week. In one of the most expensive cities in the country. I took a photo of this but I couldn’t find it to post.
