Yes, because you exchange work for money, and exchange that money for machines that do the chores for you. That's what the last 300 years have given us.

The single most significant living improvement in rural America in the 20th Century was - rural electrification. Because the housekeeper got almost their entire Wednesday back, no longer spent out on the washing porch scrubbing at the washtub, cranking the wringer and hanging/gathering wet clothes at the line.

Interesting definition. Needs expansion to address the number of hours required to perform chores. Having more hours available to do laundry isn't better if laundry takes significantly more hours.

Medieval peasants, as far as I know, did drink a lot of beer.
