This plays counter to the popular idea that rich people are hoarding their wealth in cash. They don't, the money is all in investments which create things and employ people.
I don't get why this was downvoted, except perhaps out of a silly emotional reaction. You just summed up the essence of what a large percentage of the whole comment thread for this link explains in detail in different ways. Many rich people got rich by creating growing value for others with their capital assets and they continue to do so by doing more of the same. What they "hoard" is being deployed in the economy in crucially productive ways that benefit thousands or even millions of others. Not all cases but plenty of them fit this profile among the extremely rich.
Actually in all cases. Even cash "hoarded" in a bank account winds up invested in the economy, because that's what banks do - loan out some multiple of their deposits to people who spend/invest it.
