Easy. Market competition. The plumber's competitors also get a break from the IRS. They can afford to cut prices to expand.

There is no break. You'll spend the money someday and when you do you'll pay taxes. If you cut your prices equal to the repealed income tax you've just royally screwed yourself for when you do spend it.

Price isn't the only way to compete, just ask the Big Three Automakers.

I'm a General Contractor for over 20yrs, I know how to compete.

So you're saying if people cut their prices, they won't have enough money to pay for stuff because people won't cut their prices? That is tautlogically false.
