It certainly affects them. It's their choice to be affected by it or not. The incentive for learning English is already built-in by virtue of the difficulties not learning English present. People can get by, and as such they do not need to learn English, but they'd certainly get by better and easier if they learn it. They're choice.
People don't need to pretend it affects them when someone doesn't learn English. They only d this in order to justify the exceptionally stupid stance of making it a qualification for immigration, which is what the stance of "making immigrants learn English" is. (Ironically, making legal immigration even more difficult than it is already is the single dumbest position anyone who opposes illegal immigration can take because the only result such a policy can achieve is an increase in illegal immigration. It will never do what it sets out to do because of that.)
Now, I would certainly never make the absurdly stupid argument that immigrant children shouldn't be taught English in school (which is the only possible argument I can really imagine that the evidence that you presented would refute).
To expand further, I am 100% in favor of naturalization having an English language requirement.
I just oppose phenomenally stupid ideas based on ignorance of the immigration process that would certainly cost so much money and resources to implement that they'd never really be effective so what people are really doing here is impotently pissing and moaning over the fact that they have to press one for English, which wouldn't have any chance of changing even if the requirement to learn English was in place because that's primarily a choice made by private businesses in order to make more money off of a specific demographic of people who are understandably far more comfortable speaking about important things, but especially financial matters, in their native language. They will choose to bring their business to the one that caters to them in this fashion, even if they do speak English fairly well. So that is never going to change. Businesses have figured out that it is a profitable idea. Learning Spanish will be a job requirement for a lot of jobs for the rest of the US's existence. People need to now learn the concept of personal responsibility. Choose to learn it and make yourself more valuable to the work force, or choose not to and limit your options.
