and do they? if your money is in a tax haven, you don't pay income tax there. if your ghost company from the tax haven buys a private jet, you don't pay any tax on it. if you then rent it from yourself, you can call it a business expense, and deduct it from your company's profits. if you get a loan from yourself in the tax haven, that's also tax free.

where does the paying income tax come in? rich people are always, legally speaking, on the brink of bankruptcy, and can't afford to pay tax.
