The comment above said that there are EU countries with comparable GDPs to the US. There aren’t any. I don’t think per capita matters in this particular case since the difference in gross gdp is so dramatic. There is a much bigger incentive to monopolize in the US because the pie is so damn huge that it offsets the cost of overcoming regulatory hurdles.
