The mortgage interest rates in the USA should be RAISED. There is no incentive to deposit money into a savings account or a CD. Funds would flow into banks like a busted dike if banks earned more on mortgages and could pay a decent return on savings.
Now, as long as the central socialist government’s income tax is such an outrage all deductions have to remain until the unwieldly mess of tax law is overhauled!
Note, if current mortgage rates are 3% or so, all that means is if you can find the money to borrow, and you qualify for it, you can get a mortgage at that rate. If there's no money to borrow, you can't, and if you don't qualify, you have to pay a higher rate.
The article is, of course, a piece of propaganda since it starts off with a half truth about mortgage rates, and proceeds to rearrange the universe in that light.
