The translations I can find say:

"“If anyone is not willing to work, neither should he eat.”

Not, not working, but being lazy and refusing to do necessary work. A scrounger exploiting the kindness of others. Very likely addressed to a community with limited resources.

it goes on to say:

"For we hear that some among you are living an undisciplined life, not doing their own work but meddling in the work of others. Now such people we command and urge in the Lord Jesus Christ to work quietly and so provide their own food to eat. But you, brothers and sisters, do not grow weary in doing what is right. But if anyone does not obey our message through this letter, take note of him and do not associate closely with him, so that he may be ashamed. Yet do not regard him as an enemy, but admonish him as a brother."

That's true, but the context is Xi being against Western "Welfarism". I presume (although I don't know for sure) that they're not against some support for the truly disabled, but that doesn't cover able-bodied people being on welfare for long periods, even if the employment market is unfavorable. The major exception is that Chinese people have traditionally been able to retire relatively young (in their 50s or even 40s sometimes) and receive support, particularly if they work for state-owned enterprises.

> not doing their own work but meddling in the work of others

Sounds like Stalin, Putin and others like them.
