Quite simple. In a civilized society, the people/state recognize that it is society's responsibility to insure the health of the people and to educate the population. A civilized society recognizes the value of an educated people.
In a plutocracy, such as the USA, the government exists for the benefit of the wealthy, its primary purpose protecting property rather than the well-being of the population as a whole. It's a simple question of priority.
The money spent propping up the military-industrial complex, spent subsidizing the oil industry, spent subsidizing the exportation of jobs could more than cover the cost of educating the population.
A civilized society, in your words, rumps, should pay for the need for every citizen, such as Education, Healthcare, Food?
What responsibility does the individual have towards his or her own care?
There have been countries which have done this, rumps, and have failed - Soviet Union, eastern block countries.
There are countries which are doing this now, rumps, and are having a very hard time, Greece, Spain, Italy, Ireland.
There are countries which are doing this now, rumps, and their people live in absolute poverty, Cuba, Zimbabwe.
There are countries which are doing this now, rumps, and they have enormous debt, Netherlands, Denmark, Ireland, Belgium, UK.
The US is moving towards a large percentage of debt, with its yearly GDP = its debt at present.
At some point the debt prevents the nation from growing and the taxes goes to paying down its debt and not buying goods and services. Then services become rationed. While everyone will theoretically have free Education and Healthcare, but there's no one to provide it.
This happened in the former Soviet Union. Ask anybody you know who used to live there. They waited in line to get their blocks of Cheese and bread at the Government store.
Is that what you are aiming for, rumps?
