Because each state in the US has it's own flavor of regulation (and culture) impacting most of the factors that affect life expectancy most greatly.

Your access to booze, cigs and healthcare is very different in NM than it is in MA.

It's also a very US-centric thing to think that the US is the only country with significant differences between its internal subdivisions.

You can also say the same thing about the individual states in Germany.

That is not at all the same in Germany. German states do not have sovereign jurisdiction over their territory. It is a common illusion of Europeans about how America at least is supposed to work, even if things are rather penetrated currently due to such ignorant perceptions and the propaganda that was pushed by the ruling class to cause your kind of confusion.

Think of it this way, the USA in its current corrupted form is far more like the EU that has been effectively conquering the sovereign countries through simply elbowing and corrupting its way into power through its weight. The USA is supposed to be more like the EU was up to about 2010, even though this corrupted and rotten state of the EU was always inevitable, because it was the very objective of the bait and switch operation, that especially the young of Europe have no clue they were conned with to deprive them of their freedom.

You should maybe read the Declaration of Independence and the Constitution as a starting point and then think about how they outline a structure that is different than what exists today in the USA and especially how it is extremely different from the illegitimate and proto-tyrannical EU.
