Should people who are able to work, have to work?

8. Then wouldn't the entire system unravel?

I have always thought of fFrom each according to his ability, to each according to his need" as a sort of contract between the people.

If you have the ability to work, then you should contribute to the rest of society in the best way that you can. In return for your contribution, the rest of society provides you to have your needs met.

The doctor works to keep people healthy. The farmer works to feed people. The tailor works to clothe people. The carpenter works to provide people with shelter.

In return, the ones I just mentioned don't have to worry about their health, their food, their clothes, and their homes, because society provides them with these things.

If someone has the ability to work but does not wish to contribute, they don't have the greater good of society in mind. They are being selfish, and this kind of behavior would lead to the unraveling of the whole system.
