> Why does a tax on wealth cause fewer GDP-building things to happen? The rational thing to do given a tax on wealth is to spend your extra wealth on services you're interested in, donate it to charities you support, etc.

Another rational thing to do is to create vehicles that store but temporarily impair the market value of that wealth as computed for wealth tax purposes. Put it into a private company and offer minority, non-controlling stakes in that private company to all comers and act surprised when only family members take you up on the offer. It's a minority stake without control rights; it's going to be worth less than the net asset value. Store the wealth there until you're ready to use it, then have the company directors make a distribution, or leave the transfer in place to your heirs, who will receive a controlling interest when their shares (that maybe they bought) are reunited with the shares that you will them upon death. Or invest in something illiquid and very hard to accurately value.

Technically, all of those things create GDP activity for lawyers and accountants as well, but it's hardly good public policy, IMO. (I'm not opposed to a reasonable wealth tax, say 0.25% annually on sums 10M-50M USD and 0.5% annually on sums above that. I don't think it's a tax without lossy consequences though.)
