What often happens is that corporation in high tax country has subsidiary in low tax country that they find a way to funnel profits too.

Not sure on details myself. It has to be done just right.

I believe Ireland and the Netherlands are often host countries.

Now this is different than money laundering, which is big time illegal, of course.

I think you're talking about the double Irish corporate inversion loophole, which applied to multinational companies, and was closed 10 years ago.

As a US individual you get taxed no matter where in the world you live, and you must pay capital gains on all of your assets before giving up citizenship

I believe the Netherlands one, which I don't fully understand, is still in place.

That has nothing to do with individual taxes.

Why not? I know in Poland I am not taxed until I sell the stock; and if I am out of the country for X amount of time, I am not considered a taxed resident.

I am fairly certain the US is different, but I know that I can do that in Europe.

In the US, different states have different rates. At X00,000,000 he's basically all in the top bracket so ~13.3% in California (it's taxed as income), other states have lower, some states have 0%.
