The Democrats own most of the affordability problem, due to their: forced use of high cost energy and expensive cars; blocking affordable housing construction; war on rental housing; high property taxes in urban areas; and their war on farming.
But Trumps tariffs contribute to the problem — by making the prices of the taxed imports less affordable. Hopefully, his mega tariff deals will reduce this.
We know tariffs make some products marginally more expensive. THAT IS THE WHOLE POINT. Suffer a little now and then have a productive industrial base.
You have the foresight of a gnat.
