Estimates for the US based on current tax rates and distribution 
  and using financial and energy data for 2007 at: US economy.htm
Quad Btu used per year = 102.676
One kilowatt hour = 3,412 Btu
Energy efficiency = 0.13662 $trillion per Quad used
GDP = $14.028 trillion per year in 2010 dollars
Population = 301.737 million
Average GDP per capita = $14,028/0.301737 billion pop =  46,491  $ per person per year in 2007
Energy consumption per person per year = (102.676*10^15 Btu/301.737*10^6) = 340,283,094  Btu
Divide by 3,412 to get kilowatt hours/person/year = 99,731  kilowatt hours

Medical costs will exceed all other personal costs because all individuals will have to be covered in some manner!  The US must deal with medical costs!!
   For example limit federal aid to available revenue:  US_Benefit_Pool.htm
Notes:
1. Estimated government costs with 50% benefits in the last table = 1.5 x hourly rate x 8 hours x 30 days .
2. Unemployment payments are pooled with job training and retraining as they should be.
3. Note that federal manditory budgets in 2009 totaled $2,093.9 billion. CBO_F1_F9.htm

6. US Population and GDP per capita: US_model.htm
7. OECD to US Senate Special Committee on Aging p3, 093009  OECD093009P3.jpg
8. The CIA World Factbook reports US age 15-64 is 66.8% of the population in 2011.
       This gives a ratio of (66.8/(100-66.8) = 2.01 potential workers per nonworker.
       The age 15-64 stable age distribution figure would be (64-14)/(14+13) = 1.85
       The age 22 to 64 population will actually pay almost all costs giving a worker/nonworker ratio = 1.23
9. The US needs to retrain workers and reduce medical costs for the chronically ill and aged.
10. A more rational national budget might be:
Percent of Federal Revenue %
Defense 15
International affairs 15
Infrastructure (energy, utilities, etc.) 15
Research, development, education 15
Universal basic medical care 15
Social security 15
Budget and Debt management 10
