True, but Friedman is not categorically refuting his entire life's work at this late stage in life.

There's nothing wrong with Friedman's life's work.
Nor Samuelson's, for that matter.
They are both Nobel Laureates, afterall.
It's just that Milton has become more senile and set in his ways.
He no longer has the mental agility to evaluate changing market conditions and adjust his perspective accordingly. He just chants the same old mantra, even though market conditions have changed.

It's just that Milton has become more senile and set in his ways. He no longer has the mental agility to evaluate changing market conditions and adjust his perspective accordingly.

Perhaps, but subsequent Nobels have been awared to those sharing Freidman's economics, not Samuelson's.
