Because they are inclusive, outwardly looking and commercially astute. I suppose they could call it the world tour, but Finchem would choke on his coco pops.
It was European at inception, but for the all the reasons stated it expanded:
- poor weather
- poor courses outside GB&I
- best courses in GB&I are not well located for anything less than a major
- chasing the money
- it expands their fan base as fans from the colonies are far more likely to be followers of the tour if they get a local tournament every year rather than followiing some odd travelling circus in the US
- does access some fantastic courses from time to time that are far superior to the weekly dross on both the European and US tours. If the likes of Australia, NZ or South Africa for example get one European tour event a year, then they are unlikely to waste that opportuntiy and plonk it on some 80's resort track (not an iron clad rule alas)
- because they have to, folowing the money.
-because they can as European players are actuallly prepared to get on a plane and fly somewhere where they speak a funny language
Would the US tour suffer from playing a few non-US tournaments. Def not apart from the fact none of the americans would show up
