No because the shares (in theory) have value behind them. If they went up overnight, it was because the value of the company changed not because the purchasing power of money changed. If they went up from 5K to 10K from 1996 until now, yes you could say it was inflation. But you also wouldn't pay any tax because we don't have a CGT.
I... don't know. Maybe it would?
Here's another question though. That old lady/man everyone knows of that owns dozens or hundreds of houses, do you think they ever sold any? They can still accumulate wealth without paying tax by simply hoarding it like a dragon.
That's where a wealth tax works better. Because this tax only applies if you sell, if you have enough assets and lenders are confident they'll continue to grow in value you can just keep buying more and then borrowing against them to cover your expenses year on year.
Yeah, so a wealth tax would be that every year you have to declare your net worth and pay a percentage of that as tax?
I wonder what the administration and enforcement cost of that would be. This very narrow CGT has on benefit in that there isn't really much extra admin since most of the relevant parts are already done in one way or another.
Yep CGT is a simpler system to apply I think, but doesn't address the real problem which is that once a certain amount of wealth has accumulated wealth begets wealth and the vast disparity ends up with a small class of people fully insulated from the problems their horading causes.
