Note, such so-called loopholes include such things as a progressive tax code that taxes the first $50,000 less than the next amounts over that - just like the personal income tax rate. It is people like the author above that benefits the most from such a "loophole"

The fact that he benefits from it does not mean it isn't a loophole, doesn't mean he won't call it a loophole, and doesn't mean he can't think/say it should be closed.

There are some people who care enough about their nation/society to advocate things that would be, in the short term, detrimental to themselves, because they think that those things would be in the long-term interest of their nation/society.

(No comment on whether it is or isn't a loophole.)
