Bezos *most definitely* doesn't "hide his billions" in off-shore bank accounts, he has it invested in the stock market, among other things. The reason why rich people stay rich is because they put their money to work - by investing a significant portion of their money into stock they both stimulate economic growth *and* benefit long-term.
Yeah, works wonderfully.
(Minus the hyperbole (the channel is not a good source - they are mostly out to produce outrage bait).)
The issue for a long time has been, that there is much, much more money in derivative markets, than in the real economy:

Meaning. If somewhere in the world - there is growth (lets say india), and people can be convinced to invest in 'something' that promises them a better return. But the real economy isn't going so great in the developed world. You can basically make more money, by faking other investors out (invest into something they dont really understand), signaling opportunity, then cashing out and move on, while they flood in inflating the actual worth of the opportunity. Meaning - you get rich, not because you invest in the right opportunities, but in the right trends.
Meaning - that you make more money from 'virtual' transactions (having nothing to do with investments that reach any real world economy), taking other peolpes money. Essentially - playing casino.
Meaning - if you can do that, because you find/overexaggerate an opportunity in lets stay with india as an example - none of your investment helps people in the actual economy - much less in the US (or europe, or...).
Same with that money being invested in automation, or digitization (takes away well paying jobs, doesnt produce new ones).
Meaning - currently there is so much money in play looking for returns (boomer generation looking for a better retirement), with essentially no one believing in (sustainable) economic growth in the developed world, that that money is switching hands in the derivative market, like in a casino (some people loose, some people win) - ending up with big wealth people, because they can represent an aura of 'we know what we are doing' better. (Think of chip leader in poker, not taking substantial risks anymore, while blinds dont rise - similar mechanics.)
Which means, millenials are f*cked generationally. For one and a half centuries already. No one will give them (big'ish) credit (if they are starting out). They are unable to accumulate wealth through wage growth. They cant save up (0 percent interest rates after inflation). And they are told by boomers, to life a little less, for the environment in 100 years.
The only thing they can do essentially is innovate (in an economy where no one believes in sustained growth past 10 years on any thing one can come up with currently (it seems)), consume everything they have (because tomorrow it will be worth less), and inherit wealth.
Thats it.
Oh and Bezos is actively destroying city centers and small and medium size companies - through the amazon business model - which optimizes for, everyone stay at home, and click on skinner box.

Here is where tax havens come in - because no one of the bigger wealth people believes that states can solve any of that - they now especially tend to not pay wealth- or income taxes if they dont have to.
(Also - if you make money in a casino, you are relatively fiscally mobile (not invested into the real world, much), meaning its harder to tax you. (In the internet age, you dont need suitcases with money going over borders anymore.))
