Quick & dirty calculations show that pretax income per household (just taking the national income accounts number for personal income and dividing it by the number of U.S. households) shows an average of almost $70,000 per HH. Actual median income is just over half that. If you took the top quintile (roughly the $75,000+ HH) and divided the excess of their share over 20% (their share is about 49% of the total, so the excess would be 29% of the total $7 trillion in personal income), there would be about $25,000 per household, These are electronic equivalents of cocktail napkin calculations, so I wouldn't base Congressional testimony on them, but they do give you an idea of the magnitudes involved.

No one really has a good picture of inheritance, but the studies I've read show that about 50-75% of existing wealth is the result of inheritance or the returns on inherited wealth. 50% is conservative, but 75% is far from outlandish.
