But a question remained: What would count as income and what wouldn’t? In 1916, a woman named Myrtle Macomber received a dividend for her Standard Oil of California shares. She owed taxes, thanks to the new law. The dividend had not come in cash, however. It came in the form of an additional share for every two shares she already held. She paid the taxes and then brought a court challenge: Yes, she’d gotten a bit richer, but she hadn’t received any money. Therefore, she argued, she’d received no “income.”
Four years later, the Supreme Court agreed. In Eisner v. Macomber, the high court ruled that income derived only from proceeds. A person needed to sell an asset — stock, bond or building — and reap some money before it could be taxed.
Since then, the concept that income comes only from proceeds — when gains are “realized” — has been the bedrock of the U.S. tax system. Wages are taxed. Cash dividends are taxed. Gains from selling assets are taxed. But if a taxpayer hasn’t sold anything, there is no income and therefore no tax.
Contemporary critics of Macomber were plentiful and prescient. Cordell Hull, the congressman known as the “father” of the income tax, assailed the decision, according to scholar Marjorie Kornhauser. Hull predicted that tax avoidance would become common. The ruling opened a gaping loophole, Hull warned, allowing industrialists to build a company and borrow against the stock to pay living expenses. Anyone could “live upon the value” of their company stock “without selling it, and of course, without ever paying” tax, he said.
Hull’s prediction would reach full flower only decades later, spurred by a series of epochal economic, legal and cultural changes that began to gather momentum in the 1970s. Antitrust enforcers increasingly accepted mergers and stopped trying to break up huge corporations. For their part, companies came to obsess over the value of their stock to the exclusion of nearly everything else. That helped give rise in the last 40 years to a series of corporate monoliths — beginning with Microsoft and Oracle in the 1980s and 1990s and continuing to Amazon, Google, Facebook and Apple today — that often have concentrated ownership, high profit margins and rich share prices. The winner-take-all economy has created modern fortunes that by some measures eclipse those of John D. Rockefeller, J.P. Morgan and Andrew Carnegie.
