To be in the top .1% you need a wealth of about $60m, certainly nothing to be worried about, it gives you a very nice standard of living.
But it's a lot nearer to someone at the 90%ile wealth of about $2m than the kind of power that those with $1b, let alone centi-billionaires, have. You're talking top level entertainers (actors, sportmen etc)
Good point, maybe the more important statistic is that there's 900 billionaires in America, representing about 7 trillion in collective wealth. The USA GDP is 30 trillion... the situation just seems inherently wrong to me.
