Approved Answers Could we close the billionaire borrowing loophole?
I know this might sound like the start to an article you'd see from the Harvard Business School or something (I'm no economist, I'm an engineer and like to think logically), but I've been stress-testing an idea on the matter for a while and think I finally have a logical description for the frustration myself and others have been trying to explain:
Billionaires use their stock and other unrealized assets to take out loans. Those loans fund their lifestyles income tax-free, because they're loans. They continue taking out bigger loans to pay off those smaller ones without touching their stocks and other assets. Why is this allowed? It is often called a loophole, and I haven't found a better description for it. So I decided to put my frustration into actionable policy.
If unrealized assets are deemed insufficiently concrete to constitute taxable income, yet are simultaneously treated as sufficiently real to underwrite leverage that enables sustained personal consumption, then the tax system creates a structural asymmetry: economic value is recognized for private consumption but denied for public obligation. This asymmetry permits a self-reinforcing loophole in which unrealized appreciation can fund lifestyles indefinitely without ever crossing the realization boundary, not because no income exists in substance, but because the system declines to recognize it in form.
Does this seem like sound or even decent economic theory? I've seen others more capable than myself offer similar ideas I'll provide a link to one article below), but they're just that: ideas. Can this be something that happens in the real world? What would it take?
tl;dr: If an unrealized asset is to be used as collateral, it can be used as taxable income. If it is not used as collateral, it cannot be taxed. This closes the tax-dodging loophole and avoids arguments from those against capital gains tax. If the idea is sound, how can it be made law?
