Good point. Everyone gets the benefit so only in the sense that you don't have to have a mortgage in order to enjoy the benefits do homeowners get screwed. I think the idea is to lower the number of people who have to itemize 'cause that's a hassle and often an expense of hiring an accountant. For example when I was itemizing I was deducting $18K. Since now every married couple gets $24K, I'm no longer deducting my interest but I've benefited to the tune of $6K in deductions.
