In the experiment you mention, before they put the frog in the cool water, they removed its brain. Then they boiled the water. The frog did not jump out of the water because it had no brain. The experiment proved the opposite of what you are asserting.

If every wealthy country had a frog to represent their culture of taking care of workers (strong unions, workers rights, vacation days, not having healthcare tied to their employment, maternity and paternity leave, equitable pay etc), there is one particular frog which most would describe as having had its brain removed.
