The article explores how current income tax laws might change under a consumption tax system. It looks at issues like tax-free fringe benefits, home mortgage deductions, and different tax treatments for salaries and dividends. The researchers discuss how these problems could carry over or worsen in a consumption tax world that encourages more savings. They also examine the distinctions between business and investment expenses, tax losses, and the taxation of the family unit. The goal is to see how these inequities in current tax laws would play out under a new tax regime that focuses on consumption.
