Letting it lapse means that nearly every worker will see taxes go up, but the pain will be felt most at the bottom. Two-thirds of those in the bottom twenty percent of income will be affected by it. For example, a worker earning less than $20,000 a year will pay about $100 more a year in payroll taxes—the equivalent of a family‘s groceries for a week. A bit further up the ladder, someone making $50,000 a year, about the national median, will pay $1,000 more, canceling out the $1,000 break she would get from other parts of the deal."
