This is the 64 dollar question. Between the ages of 40-60 generally these costBut who were the one(s) Paying that 300B?
are paid by individuals and their insurance plans. After 60 more and more of
the costs start shifting to the public sector. Today and into the future more of
the costs will be picked up by the public sector as the pool of decent paying jobs
shrinks and those qualified and trained to do them also shrinks.(hint we do not need
more people with BA degree's)
How the actual costs breakdown is uncertain. Some claim most is paid by the
individuals and their insurers well into their retirements. This probably still holds
true today but will not be in the foreseeable future as private retirement plans are
changed,modified or simply run into the ground or simply not offered in the first place.
One must also take into consideration so called incidental cost's such as lost wages,
which can be quantified and lost production,which can't. If Ford needs 5000 Focuses,
Ford will make 5000 Focuses.
Generally when the State or Federal governments cite costs as an expense in certain
area's such as Health,Education and,Welfare they are referring to all cost's from private
and public sources. NHE in 2014 was 3 trillion dollars.(17% of GNP) 300 billion reportedly
for smoking related illness. You can already see a discrepancy. Smokers are only incurring
10% cost to the total health care expenditures or they are paying 90% of the cost on their
own. 1.1 trillion in Medicaid and Medicare costs.Roughly 1 trillion paid by households.
17% from state,local,and other agencies.
So the short answer is,who knows.
