Yes, you do. So why add yet another worry (a 0.5% wealth tax).

Keep in mind that "flat or depreciating" companies are way more common than you think. Not every company enjoys the annualized returns of the S&P500. Almost any non-tech or non-tech-adjacent company has remained either flat or depreciated, in the last 10 years.

That's the entire reason why lay people invest in the index, because it's relatively safe from depreciation. Most of the super-wealthy don't achieve that wealth on the back of the S&P500, they achieve that on the back of owning a single zero-to-one stock. It's one thing for the company to grow from 0 to {insert equilibrium valuation}, and another thing entirely for the company to continue to grow at a rate that outpaces inflation.

The argument you'll get back though is that that 0.5% wealth tax will no longer impact you _at all_ if your asset value drops below $50M.

A 0.5% wealth tax is not going to make you poor. It could, _at absolute worst_, make you worth "only $50M". If you still manage to go from $50M -> $20M, a wealth tax had absolutely nothing to do with that.

As well, although it's not explicitly mentioned, I would expect any floor-value (such as $50M) to be set to keep pace with inflation.

Okay, $50M was just the number for the sake of the argument, but the core argument still applies for those individuals worth $100M in the same circumstance, or $500M, etc etc etc.

Your argument doesn't refute my central argument, it refutes an unimportant implementation detail.

Are you saying that most of the super-wealthy do not (at least to a certain point) diversify their investements? Or is your point that most super-wealthy individuals acquired their wealth themselves by investing (or founding) a single corporation themselves?

[bhupy]

Most of the super-wealthy derive their wealth from owning significant ownership in extremely valuable corporations. Outside of hedge fund managers and Warren Buffett, most of the super-wealthy do not have sufficiently diverse investments whose annualized returns may cover the annual wealth tax bill.
