Way to impose your own values on others and then when they don't give two ****s about your value-system you then make the argument that they must not care for themselves.
This is called 'Cultural Imperialism' and is almost always linked to bigotry. Maybe you're an exception...
Why should it benefit this country? And, further, what the **** does that even mean? The only time "benefits the nation/country" ever has a clear meaning is in fascist states: Germany, Italy, Japan. That is, the state very clearly and articulately requires that its subjects sacrifice their own individual drives and wills in order to carry out their state-imposed duties.
Do you know what the official role of the US Government is, as per its declaration to the world that it is now an independent state? Protect the rights to life, liberty, and the pursuit of Happiness for...wait for it...all men.
That is, the explicit function of the US Government, as declared in the DoI, is to protect the rights of all men (now, of course, we understand that Jefferson really only meant white males).
Further, what is good for something is usually that which helps the something fulfill its function. Thus, what is 'good for America' would be, quite literally, the protection of the rights of life, liberty, and the pursuit of happiness for all men.
That being the case, ease and efficiency of process actually plays a vital role.
In case you've never read the Founding document of the country you so desperately want to benefit, here it is:
