Okay,
I get your point.
Just to answer your question, it is because:
1. America is rich, developed and everyone loves it including those who always proclaim 'death to America'. They watch your movies and drink Coca Cola........and wear Nike.
2. America doesn't have the talent anywhere close to where Kenya is.
3. America is welcoming........or was until 2016. Yes!
Kenyans don't flock to Canada or Britain yet, the Standards of living are more or less teh same and neither do they go to Swiss, Norway, Belgium e.t.c.
Our problem is that we havetoo much talent. It is 'infinite' .
No one knows how many people we have and since a country can only send three athletes for each discipline per championship, some guys will miss out.
Ruth Jebet is very comfortable running for Bahrain. She doesn't even attempt to make the team because she is theteam and the country.
Cheserek , if he stays in Kenya, will be shortchanged. Thare is no doubt in mymind.
He will be overlooked and then, fall though the cracks.
In America, hewill almost always make the team in anything from 800m to 5000m and beyond.
I don't like it though. I think acquiring talent this way defeats the very purpose of the spirit of hte games........e.g. theOlympics movement.
Just my five shillings worth of opinion.
