That's a beautiful ruse that the elites have conjured up to defend tax subsidies! Seriously, modern day followers of Goebbels would be proud.
If you're a business, there are two ways government can subsidize you. One is to write you a check directly - we all see this as a subsidy. The other is to write into the code a special deduction or credit for your industry, or even your company (that's been done!). It's as direct and effective as writing a check, but it doesn't appear as "spending" and only gear heads who have more time than most to study the arcane 1,000 tax omnibus bill will even notice it, and there is no way for even them to see the real impact to a particular company, and we'll only see the impact on industry years later, if that. But it's as real as a direct check, just artfully hidden from view.
If I recall correctly, the biggest subsidy on the books is the deduction for mortgage interest. In general, housing isnt' deductible - it's a personal expense like electricity, TV, lawn mowing, etc. But Congress decided to allow a deduction for a very specific kind of housing - owner occupied housing, secured by a special kind of debt. We can deduct that interest personally, but cannot deduct other kinds of interest. It's a direct and incredibly large subsidy to the housing industry, with benefits that increase as the amount of debt and the income of the borrower increase. This subsidy is useless to someone paying no income tax or who does not pay enough in interest to itemize.
And the reason it's a subsidy is some people can deduct part of their housing costs, and others cannot. If you rent, housing isn't deductible. We've paid off our mortgage - and get no housing subsidy. So it's only a special type of person who can deduct housing - we are subsidizing housing for that group, but not for others.
What we should do is calculate the amount, and send checks, the largest to the most indebted home owners who report the highest incomes. We might still keep that subsidy in place, but the public wouldn't be fooled that a tax deduction for mortgage interest is somehow different. It's not - the effect is identical to sending a check, and if the effect is identical (and it is) they only differ in form.
