Contrary to popular belief, it wasn’t slaves who built the pyramids. We know this because archaeologists have located the remains of a purpose-built village for the thousands of workers who built the famous Giza pyramids, nearly 4,500 years ago.

While I think the evidence they cite is rather weak it’s well agreed upon that the workers were paid and enjoyed elevated status in society
It’s not really a consensus, it drives higher inflation (people are spending more) and a lot of stimulus vs tight purse economics are just doing the opposite of what they did in response to the last crash
What I think they are talking about is UBI which in limited pilot projects haven’t impacted inflation
The real benefit of uplifting the poor is that it creates a safer society for everyone and faster innovation in that society because people have time/money to do things. When flying was in it’s infancy a lot of farmers in the US had hobby planes and gliding/eventually flying was built off being accessible. Aviation laws get in the way but it’s completely foreign to think of some poor farmer in rural USA being a hobby pilot today
