Per someone else's comment, then, explain Manhattan having such sucky speeds.
Unless you stipulate there's a goldilocks population density; if it's lower than that you don't get the investment, if it's higher than that there's too many people for the amount of spectrum/infrastructure. In which case, fair enough; are the places in the US that fall in that zone reaching speeds equal to Switzerland? I would contend no, not consistently, but of course, I'd need to know what that zone is.
I don't think prices are a good comparison. You will have much higher prices in places where wealth exist. There is much more wealth in the US than Mongolia or Russia. Maybe a percentage of total income would be the best comparison.
Edit: removed population density comment because people were inferring an argument or defense from it, when that was not the purpose of it.
