Nothing new there.
What productivity improvements have opened up is more opportunities for developers. Larger and more complex systems can be built using better tooling.
to what end, make rich people richer?
So, in perfect theory land, people get paid because they provide value. That obviously breaks down at the extremes.
But, for sake of example, let's take Uber, super easy to hate on them, but they have had a measurable impact on reducing deaths from drunk driving. That obviously provides a lot of value to people.
Likewise, it is hard to overstate the value people have gained from smartphones, Apple has made a lot of money but they have also provided a lot of value. Arguments over if the individual value brought is long term good or bad for society are a separate topic, but people value their iPhones and therefor they pay for them. No way could something as complicated as an iPhone have been made with 1970s software engineering technology.
