In a global economy we want global standards.
who is "we"? The "global community"?
And even if there were no international interactions, the metric system is far easier to understand and use. Clinging to the more difficult and arcane is pointless.
so what? what do you care if somebody in minnesota wants to use us customary units, because they prefer it? do you think they should be made to use a different unit, because they are being difficult and arcane? you see what I'm getting at here... it's one thing to agree that metrics are more sensible, but its another thing to force change on people when it doesn't benefit them. The US is all about self determination!
