Well I would try and figure out why life expectancies are declining.
If it’s from drugs or being obese well I can avoid those as can my family.
Not saying the info isn’t out there I just haven’t looked.
<editing out "decreasing" to substitute with "diverging lower compared to other OECD countries". Absolute "decrease" is not a long trend, but only seen in a few spots>
I have partly looked into it.
Life expectancies are diverging lower compared to other OECD countries since Reagan. That is when the US healthcare cost and quality diverged from other OECD nations (i.e. cost diverged upwards, quality diverged downwards), partly due to Reagan's anti-american and racist policies.
I have seen credible-sounding claims that Obamacare slowed down the life expectancy divergance when it decreased the number of uninsured but was overshadowed by the opioid crisis. However, I have not seen any data personally that would conclusively prove this.
With any Republican president (which Trump is) it is a foregone conclusion that life expectancy will diverge even lower or possibly even outright decrease when he weakens Obamacare and increases the number of people without insurance.
