Networks are in the business of eyeballs. Not worrying about what is acceptable. Whether you want to deal with it or not, there is a large population that speaks Spanish.
This is true of all business and this country is run by big business. They don't care what your race is, or what language you speak. If they can tweak something to increase sales, they are going to do it. How about all the premier league programming you see on the top tier networks these days? Even the latest Century Link advertising is aimed clearly at hispanics.
From an economic standpoint, illegal immigration is also the result of big business and our politicians. In an ever more global economy, those companies require cheap labor in order to compete abroad. What they don't want to do however, is make those people citizens. As soon as they do that, then the government is on the hook to take care of them, along with all the rules and regulations (ie taxes) that business has to follow. It is however only a short sighted solution to the labor problem, as the labor savings only works for one generation. The next generation will be citizens.
The language and culture will also be affected. Spanish won't take over as the dominant language, but certain words and phrases will impact pop culture and meld with current cultural norms. Again, this is a one generation change, as the next generation of children will be taught english and it will be their first language.
One way to try to visualize how things will look in the future, is to look back at our past. Slavery and the plight of African Americans was very much about some of the similar things in the beginning. Inexpensive labor for big business. They too started off with little to no rights like todays illegal immigrants. One can also then realistically predict how things will change in the next generation, when those workers do have rights.
I guess to me, it's a difficult problem and one that isn't easily fixed. I'm not sure it is even easy for people to agree on which aspects are considered the problem or are most problematic.
What is clear however, is it does come full circle. What starts as an economic advantage, turns into a economic norm, then it becomes an economic dependency.
ESPN is in serious financial trouble as we have all heard by now. They need to be able to justify higher prices for advertisements on their network and one way to do that is to increase the size of their demographic. Adding this huge latino demographic is one way to do that, and sort of brings us full circle. They will become dependent, as other businesses have on this latin demographic.
Trump already knows this, he's saying what a lot of Americans feel, but this isn't something he can really stop and he knows it. He basically says he will secure the border, deport everyone and then only let the good ones back in. While this makes the general American population feel good, it also means he understands how dependent we have become on that labor and latin demographic. Not just in sports, but in many aspects of our daily life.
Apologies this is long, but wanted to share some thoughts on it.
