No I haven't proved your argument.
Firstly those numbers are HOUSEHOLD not individual incomes so your guy is doing very well indeed because most households are two income households these days.
http://en.wikipedia.org/wiki/Affluence_in_the_United_StatesThe 2005 economic survey revealed the income distribution for households and individuals whereby the top 5% of individuals had six figure incomes (exceeding $100,000) and the top 10% of individuals had incomes exceeding $75,000.<4>
According to INDIVIDUAL incomes your guy is in better than the 95 percentile.
Secondly:
Here's a more finely broken down set of HOUSEHOLD income numbers for you:

$100,000 to $149,999 11,194 9.89%
$150,000 to $199,999 3,595 3.17%
$200,000 to $249,999 1,325 1.17%
$250,000 and above 1,699 1.50%
Interpolating the $100-$150k bracket linearly gives:
9.89% x (1-0.4) + 3.17% + 1.17% + 1.5% =11.774% of HOUSEHOLDS make more than $120k - assuming that we can linearly interpolate in the $100k to $150k bracket - that's not really very likely to be true however - in reality the numbers go down as you go up so it could well be more like 10%.
Your straw man is well above the median household income much less the individual income - he's in the 90th percentile of HOUSEHOLDS and the 95th percentile of INDIVIDUALS.
Finally re: MILLIONS of people making >$250k.. not really. Maybe a million.
http://en.wikipedia.org/wiki/Affluence_in_the_United_StatesThe top 1.5% of households had incomes exceeding $250,000 with 146,000 households, the top 0.12%, having incomes exceeding $1,600,000 annually.
