This quote at the end of the article provides a good summary of the issue:
"Pensions and access to health care remain social goods that a decent society will try to provide to its people. But goods are not rights."
The distinction between social goods and rights is an important one. It is important for an advanced society to ensure some minimum standard for its people, such as a minimum wage, a standard workweek, and basic/emergency health care. But these are not rights, and when people begin to insist on equal health care or generous benefits for all, they find that it soon becomes prohibitively expensive.
