You realize how many of those Hispanic families are illegals and pretty much can't accumulate assets?
The Hispanic population of the US is
54 million, July, 2013. Estimates vary as to how many of the total are illegal, but the best that I could come up with is a total of
~12 million illegals total are in the US, down from a peak of 13 million due to the success of the previous administration in driving us into the worse recession since the great Depression by the benign neglect of properly enforcing the regulation of the financial sector, the single largest reason for the decline in illegal immigration that they managed.
Let's generous and say that 75% or 9 million of the illegals are Hispanic. The closest that I could get to an estimate here was that about 52% of the illegals or about 6 million are from Mexico. So my estimate is probably high.
The best estimate that I could come up with for the size of a
Hispanic family in the US is about 3.87 people. (Although as you will soon see this doesn't matter.) If the wealth of an average Hispanic family is $1300 then the total wealth of Hispanic families in the US is,
total wealth ≈ (54 million/3.87) × 1300
if you are correct and illegals cannot accumulate any wealth, a somewhat dubious proposition since that is the very reason that they are here, then this wealth would be shared by only,
no. legal families ≈ (54 million - 9 million) ÷ 3.87 families. So we now have,
wealth per legal family = total wealth ÷ no. legal families or,
wealth per legal family ≈ ((54 million ÷ 3.87) × 1300 ) ÷ ( (54 million - 9 million) ÷ 3.87)
Which reduces to,
wealth per legal family ≈ 54 ÷ (54 - 9) × 1300 ≈ $1560
So basically it doesn't make a big difference to the idea in the chart, that minorities have accumulated much less wealth than white families.
And this is accepting your rather dubious assumption that the illegals here don't accumulate any wealth is correct, that they spend everything that they earn, sending nothing back to their home countries. Making me wonder how all of the shops that advertise in Spanish that they do that very thing, wire money to points South of the border, how they can stay in business.
