I concur with you FT. I never believed that the forbes list is realistic. I am certain that there are many others that are wealthier than those people, but these are the ones at the focus, that's why everyone understand them and consider them as wealthy as their prosperity is calculated and everything associated with their business is documented. I am certain that there are many others that are wealthier but the amounts are concealed or un-documented so no one understand how much they have.
Another Little tip, Warren and Bill are short the USD, fine. But this does not mean that they are correct or must be correct. That is 1 thing. Another thing is that they are the USD for the long haul, which means that they might be for the next few years. They might turn out but after 3 years from today, and if this moment comes, forums will be full of threads stating that Warren and Bill anticipated the USD recession 4 years before.
Thanks,
