>the result of changes made in the 80's, like gutting anti-trust.
The '90s didn't help a lot either. cf. the repeal of Glass-Steagall[0] which, arguably, did much more to damage the US economy (there's a direct line from its repeal to the 2008 financial crisis) than a lack of anti-trust enforcement.
That said, dismantling anti-trust enforcement (which was pretty hit or miss anyway) didn't help either.
