USA HOUSEHOLD WEALTH AND DEBT

In 2000, USA household wealth was $44 trillion and rose to $65 trillions in 2007 or equal to 108% of world GDP or twice the value of world trade or 4 times the world's energy consumption by $ value. It fell by $18 trillions and has recovered $5 trillions, though debt has fallen little. Household debt was 20% of USA household wealth in total and then rose to 28% before improving to 24%. But that's only the average. A fifth of the population or of households are too poor to have bank debts. Half the population had net wealth and now don't. Som will be dwelling on a 'lost decade' if they only think in money terms? They're the so-called middle class that both parties remain desperate to help and woo for votes. The Democrats also want to do something for the poor at least in health care insurance reform.
The USA has about one third of world wealth and a similar proportion of world output. Roughly 10% of the population own 70% of US wealth, top 1% own 40%. The bottom 40% owned less than 1% of the nation's wealth, half of whom own nothing valuable!
When it comes to debt that is not distributed in the same proportions as wealth, but will be concentrated in the middle of the US household population. Do not assume that income tax is exactly proportionate to wealth distribution either. The top richest 1% pay 33% of federal income tax; the next 9% pay another third; the next 15% pay 22% of the income taxes; and the next 25% pay 33% of income tax. The next 10% pay 3% and the last 40% pay no income tax, but a lot of sales tax and local taxes for which they get something in return, maybe most of it somehow, let's hope so. The US has a progressive tax structure which taxes less for smaller incomes. But the US does not directly tax wealth except the estate tax (what in UK is called death duties and inheritance tax).
A quarter of households retain net wealth and are rich of which the top fifth (5% of all households) had under 10% loss. The top 1% may feel that in real terms or at least relative to everyone else they are in serious profit gains from buying distressed assets at discounts that will do well for them and their heirs in the future?
