As they point out in the article though, its possible for them to take out very substantial loans using that stock as collateral, effectively giving them a way of realising those gains without having to actually sell the stock and pay capital gains tax on it. They even get to offset the interest on those loans for what income tax they do pay.
Then the author should have written an article focusing on the stupidity of allowing loan interest deductions, not charts of unrealized capital gains trying to conflate it with income.
Doesn't matter if you take out loans against those gains, they will be taxed eventually when sold.
