What are the main contents of scarecrow travelers?

The Scarecrow is the work of Mr. Ye Shengtao, and The Traveler is an article in the Scarecrow.

Voyager tells the story of a traveler who travels around various planets. After traveling around the planets, he came to the earth. The warm reception of the earth people made him feel very interesting, but when there were poor people, he was very confused. The receptionist explained that the other party had no money.

The traveler thinks that the way people on earth exchange money for things is not smart. He wanted to leave, but he was kind to him because of the hospitality of the earth people. He thinks he should try to help them in return for their kindness.

Later, the traveler brought a machine map, taught factory workers to make many machines and taught people how to use them. This machine can cultivate land and make utensils. It's very successful and easy to use. People who want to use things go to the machine and press the button to get what they want, which makes people on earth forget the money for changing things.
