I am a Canadian undergraduate student intending to get a master's degree, but not intending to get a Ph.D.
A Canadian graduate student told me that master's degree in the US are really only designed for people desiring to get a Ph.D.
Is there any truth to this statement? Do masters degrees in the US put significantly more emphasis on preparation for a Ph.D than in other countries?
It's the other way around. That's because America is a nation of "doers" at least compared to Europeans.
MANY U.S. Master's degrees are terminal degrees. Think of a Master's as a "two year graduate" degree, just like an associates degree is a "two year college" degree.
Americans don't like to spend more time on education than necessary. There are Master's programs that lead to PhDs. But something like 40 percent of students in "non-terminal" degrees are foreign, not American, born.
You seem to fit the "American" mold.
