We can only do so much, as there are limits.  Therefore, we must have priorities (poverty, health...).  The following is designed to give a perspective on the relevant numbers.  
See Wealth Distribution at the bottom.
Aggregate debt in US:                $50.7 trillion
(3.5+ times the annual gross domestic product of the United States; 2009 debt owed by US households, businesses, and governments
  
Domestic financial assets           $131 trillion 
Domestic financial liabilities     $106 trillion (as of the first quarter of 2010.)
Tangible assets                          $56.3 trillion.
(in 2008 (such as real estate and equipment) for selected sectors totaled an additional )
Net worth of U.S. households   $51.48 trillion (end of 2008)
U.S. consumer Debt:  
    Mortgages & credit-card debt    $13 trillion
    (123% of after-tax income. In 1995, for instance, it was 83% of income.)
 
 
Pretax median household income  $50,233 (2007)
 
Per capita GDP (PPP)                   $46,381 (the 6th highest in the world)
Labor force                                   154.5 million (includes unemployed) (2009 est.) 
Ease of doing business - 5th
 
Exports, Jan 2012                         $180.8 billion 
Imports, Jan 2012                          233.4 billion
Trade balance deficit                        52.6 billion  (annual rate $631 billion)
Money supply                            M1                     M2
      Jan, 2012                         $2.23 trillion       $9.765 trillion
      Feb 2010                           1.71 trillion         8.53 trillion
      % increase                         30%                  14%
 (More M1 money = more dollars floating around = "printing money" = potential inflation;  M2 adds savings accounts, non-IRA, non-pension)      
Wealth effect of financial collapse:
Between June 2007 and November 2008, Americans lost an estimated average of more than a quarter of their collective net worth.  Since peaking in the second quarter of 2007, household wealth is down $14 trillion.  [The Fed also said that at the end of 2008, the debt owed by nonfinancial sectors was $33.5 trillion, including household debt valued at $13.8 trillion.]

As of 2007, the top 1% of households (the upper class) owned 34.6% of all privately held wealth, and the next 19% (the managerial, professional, and small business stratum) had 50.5%, which means that just 20% of the people owned a remarkable 85%, leaving only 15% of the wealth for the bottom 80% (wage and salary workers). In terms of financial wealth (total net worth minus the value of one's home), the top 1% of households had an even greater share: 42.7%. Table 1 and Figure 1 present further details drawn from the careful work of economist Edward N. Wolff at New York University (2010).
