Even if what you’re saying is true, this just goes to show how badly we need to rein in the ultra-wealthy by taxing their unrealized gains. Like I’ve pointed out elsewhere in the comments, letting billionaires (some of whom will soon be trillionaires) get away with having tax-free spending power disenfranchises the many people who labor for a living. The very fact you so casually say “their media outlets” just goes to show how their concentrated wealth threatens the public discourse. As a society, we can’t allow people to use their wealth to influence government and civilization as a whole without at the very least being able to tax said wealth. The solution to taxing the rich isn’t to downplay the issue for electoral convenience. It is to educate and build a grassroots movement that can oppose the power of concentrated media ownership. The very points you make kind of undermine any principled opposition to taxing unrealized gains.
