To continue with the text of the article, they found:
“Nearly three-quarters of these US-based economists oppose a federal minimum wage of $15.00 per hour.
“The majority of surveyed economists believe a $15.00 per hour minimum wage will have negative effects on youth employment levels (83 percent), adult employment levels (52 percent), and the number of jobs available (76 percent).
“When economists were asked what effect a $15.00 per hour minimum wage will have on the skill level of entry-level positions, 8 out of 10 economists (80 percent) believe employers will hire entry-level positions with greater skills.
“When economists were asked what effect a $15.00 per hour minimum wage will have on small businesses with fewer than 50 employees, nearly 7 out of 10 economists (67 percent) believe it would make it harder for them to stay in business.”
What about the “universal basic income”? Two countries, Canada and Finland, recently tried it. Both stopped.
