According to [0] there were 73,110 ultra wealthy US citizens in 2017, i.e. individuals with more than $30m in net worth. The same article says that the average net worth in this group is $120m.
In aggregate this group thus controls 120m * 77 110 = 9.3 trillion dollars.
Since there are around 330m people living in the US this would amount to only a little over 28k per person when redistributed.
