So you really think the Democrats will ever make things affordable? What a joke. You should move to California and see how affordable it is.
What they will do is force states to make things appear more affordable by manipulating things like the housing market, health care insurance, energy prices. It will be a shell game. Their answer to the housing market will be rent control and increased mandated “affordable housing”. Their answer to health care costs will be mandated insurance with much higher penalties to those who opt out. Get ready for “Medicare and Medicaid for all.” Their answer to higher food prices will be removing income restrictions from SNAP. Their answer to energy prices will be pushing for “green” energy and banning any decentralized power options.
But where will the money come from? Look in the mirror. I think we will see a national VAT in the next few years.
There are plenty of blue states that are affordable, even California as long as you are not in one of the major cities. Same for New York, Mass, and so on. It would help you to get out and travel a bit.
