We have, yes. If you notice things to be too expensive it's a result of class warfare. Have you noticed how many people got _obscenely rich_ in the last 25 years? Yes, that's where money saved by technology went to.
It may result in class warfare but I am skeptical that's the root cause.
My guess is it has more to do with the education system, monetary policy and fiscal policy.
This class thing is especially identifiable in Europe, where assets such as real estate generally are not cheaper than in the US (with the exception of a few super expensive places), yet salaries are much lower.
Taxes tend to be super high on wages but not on assets. One can very easily find themselves in a situation where even owning a modest amount of wealth, their asset appreciation outdoes what they can get as labor income.
