How will this help a resident of kibra slum, to get a bread ama unga, hivyo kabisa
Your question is valid, but remember somethings are not as direct as you want them to be. But this is how it works!
1. Talent search:
When we expose our country to such organizations like La liga and Premier league, interest is developed in our country, you saw our boys play in the premier league against Hull city, in the next few months they will play against Southampton, Arsenal coaches have been and some still in Kenya, Our boys, from Kibera will get a chance to join better clubs just like kina Wanyama and they will get money to build their Kibera.
2. Advertising our country:
When our name is all over Europe, On every television in Europe, People get to know more about Kenya, Some who had bad information about Kenya starts changing their notion. They will appreciate that if Kenya is sponsoring their league, then it is a good country. This makes Kenya famous and improves Foreign Direct Aid. Many investments increase in Kenya and the Kibera population gets employment and betters their livelihood.
3. Association:
By so doing, Kenya is creating a bond of association, People always associate with people who are close to them, people in Europe will find it easy to buy products from known origins, If they see our boys playing with a Maasai arm band, they want also to buy, then a juakali artist in kibera who makes such products gets it easier to sell and open up his market employing more population in Kibera. For example people at Hull city will easily buy a T-Shirt written on Kenya' than that written on Tanzania, we call it Association.
The importance of such things to a country is enormous my friend, i can write a whole essay on the same. Those are just a few.
