Printer's right. It's not a matter of percentages or fractions. It's a matter of what parts of what parts of what parts... It requires specifics. A better poll would be in what area does government most belong or most need to stay out of. Even then, no poll can really capture the complexity of the issue.
Also there is a difference between "should" and "could or couldn't"
I'd say government SHOULD play practically no roll in our lives. But that ideological statement would be severely ignorant of reality.
