Should billionaires be allowed to exist?

The moral argument is actually the simple one: nobody earns a billion dollars. You can be brilliant and work eighty-hour weeks for fifty years and you won't produce a billion dollars of value with your own hands. A billion is what happens when thousands of workers, public infrastructure, and network effects get funneled upward to one name on the cap table. The labor theory people and the market people can fight about the details, but the scale isn't "earned" in any sense the word normally means. What worries me more is what the money buys after it's made. Billionaires don't just have yachts. They have private leverage over the rules themselves. Look at lobbying spending in any cycle (OpenSecrets) and ask who can afford a permanent seat at the table. One person with ten billion dollars has more political gravity than a million organized voters, and that breaks the basic premise of one person, one vote. Extreme wealth concentration is a slow-motion transfer of sovereignty.
