alt Hacker News.1% hold 12.6% of national wealth so that's 300,000 people. It tends to clump at the top, apparently.
In any case, it seems a bit bizarre to me that the wealth is distributed so unevenly. Do you believe those 3 million people work so hard that their value is that much higher than the combined output of 297 million people?
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)
