the laying flat movement has mostly to do with lack of jobs/opportunity for young people.
- there's a societal trend to not hire people over the age of 30-35 in China. after months of looking for work, they've given up
- there's an unofficial 70% youth unemployment rate, and with 12 million new grads each year and intense competition for government work, sometimes hundred of applicants for a single stable government spot, the new grads give up
- the young generation has realized that no house/car/marriage/kid (没房没车没妻子) is a good way to live, and there's no pressure on them to create a life. so they lay flat. thus the abysmal marriage/child rate in China, which is near the bottom of world ranking
- the new grads don't want to work in a factory, day or night shift, for $2/hour.
- if the workers are in 1st tier cities, they can barely save up any money working and living there, due to the recent 50% reduction in wages ($1000/month -> $500/month) and increased spending on necessities. so it's easier for them to just not work and live off of parents.
