"Technology increases" have not made my life better than my boomer parents' and they will probably not make the next generation's lives better than ours. Big things like housing costs, education costs, healthcare costs are not being driven down by technology, quite the opposite.

Yes, the lives of "people selling stuff" will likely get better and better in the future, through technology, but the wellbeing of normal people seems to have peaked at around the year 2000 or so.
