Epidemiologists look only at the pandemic aspect. Politicians should look at the economy, the welfare, the general health, the strategic issues, and more. If you really think that an epidemiologist's response will account for things like mental health of toddlers you are mistaken.
I know that politicians have a bad name today but they are still elected officials who have an incentive (elections) to do what's best for the country as a whole.
Just to clarify- it was epidemiologists who pushed, understandably from their point of view, for the same lockdowns you define overreaching. It was mostly politicians who were the most reluctant to apply them. And the pressure in this direction was mostly from populism (Trump, Bolsonaro...), and from the finance/treasure ministries which feared the economy crisis.
Those aren't the same. The vast majority of politicians will almost always favor short-term "free candy!" decisions that they know will be popular with their base come election time, rather than make difficult decisions that would actually improve the quality of life for their constituents over even the slightly-longer term.
Possibly there is sampling bias with the podcasts I’m listening to and the people going on them.
I think you got it exactly backwards. Politicians have successfully scapegoated themselves via epidemiologists (who's first and last consideration is to minimize infections) and people who refuse vaccination (even though the vaccinated are still just as epidemiologically relevant.)
