You are a successful capitalist and pride yourself on getting rich by investing your capital better than most. You are also politically savvy enough to see which way the winds are blowing: not necessarily to your advantage. So you agree that something has to change to make the economy work for everyone, or at least to keep the pitchforks locked up.
What change should you support? Paradoxically, you may want to endorse a net wealth tax.
It seems certain that the tax burden on capital owners is going to increase. The determination to spend more on public services and investment is at its strongest in decades. So is the sense that when capital wealth has grown much faster than incomes have (wealth to gross domestic product ratios have doubled since the 1980s), the relative contribution to the public purse should follow suit.
