Non ironically, the problem is quantitative easing and the paradigm post 2008.
Since then, interests were lowered and money supply was increased. This means that assets such as real estate, bonds, stocks, appreciated while wages stagnated.
Thus asset owners (homeowners, stock investors, property owners) saw their net worth balloon and non-asset owners (renters, young people, low-income workers) saw their living costs rise without corresponding wealth gains.
It is working as designed.
