I think there's a little more to being rich than just saving your pennies.

There is more to becoming rich, yes, unless you're born into it.

Regardless, it doesn't change the fact that he witholds tens of billions of dollars from circulation. All that money is tied to his name and remains stagnant and useless there. The wealthiest 1% of the population which he belongs to hoards a majority of the world's wealth in this fashion, leaving a small remainder that can't support the population that is forced to compete for it.

Most of his net worth isn't in liquid assets, though. The bulk of his wealth is tied up in securities, since that's how he makes his living. Certainly, one can imagine that the dividends from those stocks and bonds are plenty enough to enrich him, but it isn't like he can just go out and buy a ten billion dollar car at the drop of a hat.

In other words, it's not quite cash in his wallet or sitting in his bank account waiting to be spent. So what?
