President Joe Biden (D), through his Press Secretary Jen Psaki (via her daily press conference), said that it’s unfair and absurd that businesses should pass on to their customers the costs represented by higher taxes that Biden and his fellow Progressive-Democrats want to impose on them.

There are some…who argue that, in the past, companies have passed on these [tax] costs to consumers. … We feel that that’s unfair and absurd, and the American people would not stand for that.

Why shouldn’t businesses pass on the costs represented by taxes?

Biden’s claim raises additional questions, too. What other costs does Biden consider unfair and absurd for businesses to pass on to their customers? What is Biden’s limiting principle regarding passing costs on to customers?
