evidence: Trump is right that home affordability is currently at a low point, but economists say his constant harping about inflation under the Biden-Harris Administration is misleading and that his plans could actually worsen the situation. While Harris said his "national sales tax"—a label her campaign has given to his tariffs plan—would raise prices on middle-class families by almost $4,000 a year, an August estimate by the left-leaning think tank Center for American Progress placed the annual burden per household between $2,500 and $3,900, while the Peterson Institute for International Economics estimated the cost on middle-income households to be more than $2,600 per year.
