I like to point stuff like this out whenever someone compares an entire EU country to some US state.
note: i edited the france density, as i did accidentally transcribe the wrong value. France is slightly denser per sqkm.
It seems like you're mixing density units.
France has 66M people for 547k km^2, which is 122/km^2 , California has 39M for 403k km^2, which is 97/km^2.
I have a 5gbit down, 900mbit up connection with 200 tv channels a d a landline for 30€ over fiber. And I'm not even in a big city
In the US I had spectrum at 80$ a month for just internet at like 20mbit down or something...
So imagine if France couldn't go into debt - only the EU can. France wants a giga-train suddenly, so they ask for it. The current leader of the EU isn't a fan of more trains, so he turns it down. France goes back to its people and says "we can build the giga-train if we do XYZ", and people vote based on whether or not they want XYZ or the giga-train more.
I think it's possible you just might want things different from what others want. That study a while back which showed most Americans want cheap public transit so that everyone else gets off the road and gives them more space lives rent free in my head. Nobody wants these stupid trains.
A popular one is 'density', and, okay, maybe this is somewhat true if you're talking about, say, Wyoming (though I think not as true as people often think), but California, for instance, has an only slightly lower population density than _France_, and at that point "we can't have proper transport/telecoms/whatever because density" is just an excuse, and not a convincing one.
