In 1940, when the weekend was implemented in the United States, the real GDP per capita was 10,027.46. Today, it is 58,024.99.
With a 5.8x increase in productivity, we should be able to work significantly less then we did in 1940.
Giving people less time to do things for themselves actually increases the GDP, because it means they are paying others to do things they would rather do themselves. Then someone gets to make a profit on that, so this type of thing is encouraged by our economic system.

That's not where the money goes. That stuff's nothing. You can get working TVs all day long for peanuts on Craigslist. I just last week grabbed a hell of a used business workstation PC on Ebay and threw in an SSD for funsies, under $200 total including the brand-new SSD. Thing screams for all normal tasks. Will probably last years. Basically nothing in the scheme of things. Can someone on a low income reasonably buy one on a whim? No. But having a TV, phone, and computer is not why people are poor.
Housing, medical care, child care. School (see also: housing costs). Those are expensive. Our modern conveniences are nothing in comparison.
