If a company can't recruit college students at all, it can only recruit people who haven't attended high school. Or people who loaf around in technical secondary schools.

No, you're mistaken. It's not that the company can't recruit people, but it doesn't recruit college students at all!

Many electronics factories are like this. Ordinary workers only need to recruit junior high school students, not people with high academic qualifications, saving labor costs.

But don't think you can muddle along. Ordinary workers are very hard. They work 12 hour a day, six days a week and work at night once a month. Basic salary+overtime pay, only about 4500.

It is unstable for factories to lay off employees when they can't receive orders.

Many people do this just to make a living, not really without the risk of unemployment. Society is far more cruel than you think.
