@DistinguishedSocialCommentator ,
Unless you are actually arguing against tax, the only question is how much to take and the fairest way of taking it.
Throughout this, you are making the assumption that wealth is a measure of talent and ambition and that tax is a random unfair thing that thwarts this. It is, in part, in that most (but not all) rich people have some talent and most poor people (but not all) have less, but it is a really weak correlation, and gets weaker the more wealth can be passed down through generations. How many rich thickos do you know? I certainly know plenty!
Most economists would rather optimise on economic growth rather than increasing wealth for the few. Aspiration is possible where you get social mobility, which means allowing people to become wealthy, not just keeping the rich rich forever.
If you look at mean productivity, the U.S looks like a success of low taxes, but if you look at median productivity (a better measure), it suddenly looks a lot less impressive and the GINI coefficient is horrible, suggesting fewer and fewer people earn more and more wealth.
If houses were taxed, people would be more inclined to trade down and swathes of empty property in Central London, which are currently owned by very wealthy (often dodgy) foreigners, would become at least income generative, and maybe made available for actual residents. In addition, large family houses would be sold, making them available for the next generation of families.
We have a sick obsession with property value in this country, which is economically destructive. The effect of super high property prices is to keep the next generation our (except for a few very specific overpaid professionals), not to help the economy.
