A wealth tax would have a significant effect on the economy’s distribution; if anything, the tax is likely to be pro-growth, and it’s more likely that any slowing of growth would be small-- if at all --and more than outweighed by the return that the economy would get on the programs that a wealth tax would finance, like education, scientific research, infrastructure and more. Those basic investments all have a long record of lifting economic growth. The very wealthy, however, don’t tend to spend much of their money building roads, starting community colleges or financing clean energy.
