> Yeah. Almost all innovation and economic improvement has only helped the upper classes and in many cases actually hurt the lower classes.

When my parents were born, something like 30-60% of the homes in their states didn't have indoor plumbing.

I meant to add "in the last 20-30 years".

Back in the 1980's only the rich had mobile phones.

Well, that's over 30 years, but yes, I think we can come up with examples. Broadband, videocalls, "free" (bundled, unlimited) long distance.

I remember when I first started seeing people with broken ankles/feet using those one-leg scooters. It took us until the 2000s to think of that!
