The whole report is here: https://www.akamai.com/fr/fr/multimedia/documents/state-of-t.... Other interesting statistics: 48% of American connections are above 15 mbps; in Germany its 33%. Maryland, which has almost exactly the same population density as Germany, is at 60%.
Imagine
scenario 1
3 users with gigabit 4 users have dialup 3 users have nothing
Scenario 2:
4 users with gigabit 6 users with nothing
Scenario 3: 10 users have 50 Mbps
In scenario 1 the average is 300 even though only 30% of people have real internet access and 70% either can barely send email or have nothing at all. Scenario 2 is even better at 400 even though most people have nothing.
Another way to look at it is that one person with gigabit is as good as numerically as 20 people with real internet or 100 people with basic internet.
While in general I agree that competition is great - I don't think that applies to the last mile (from the next PoP to the customer).
Lets start with Germany.
Internet (60 Mbps or More, Unlimited Data, Cable/ADSL) 25.92 € or 30.59 usd

United States
Internet (60 Mbps or More, Unlimited Data, Cable/ADSL) 56.60 $
Further in the US only 80% of households had a broadband connection at home or access to a smartphone with data.
In Germany its 98.
In summery the internet is almost twice as expensive in the US and lots of people don't even have access to it.
We could go through all the countries you listed and see if we could find even one where your assertion is correct but I feel like that would be a waste of my and your time because its not clear that being able to find even one nation in all of Europe worse than the US would prove that private competition has served the US well. It hasn't.
