A. It becomes more difficult for U.S. citizens to get health care.
Explanation:
If people cannot have access to healthcare, there will be more illnesses/injuries and it will decrease the standard of living. If people start traveling to different states, that won't affect the standard of living in any way. If factories begin producing goods at a faster rate, it will be convenient for people. I don't know what the gold standard is but I'm assuming it's a good thing, so that isn't the answer. The only negative thing is answer choice, so that is the answer.
