Sorry mate, no can do... I'm using an iPad... No Flash!

Odd then that "real" slavery is still just as relevant in the places where it has always been a tradition... Africa... Arabia...

Whilst "wage slavery" has become standard practise everywhere else, and it ain't going to disappear any time soon. For most people, there is no alternative to selling one's soul for a mass of potage... And the vast majority are two wage packets away from bankruptcy.

The real problem with copyright and patents, is that each is retained by the owner for too long... Don't forget that many owners are companies, and they are effectively immortal.

In the case of copyright, ten years is ample, and yet Disney and others have managed to get it lengthened in the recent past. Whilst patents (particularly software patents) are far from universal, even though the EU are attempting to introduce them, presumably in a game of catchup with the USA.

The metric system is basically the "Napoleonic" system... And the original concept of the "little emperor" was to metricate everything ... Days of the week... Hours of the day... He decreed it and his lackey's couldn't deliver... This is not universal... Even his original definition for a metre has been re-defined on more than one occasion.

You say it is easier than imperial, to do sums... Well, that may be the case in theory, but whilst we Brits were using imperial for the thousand years before Napoleon came along, and please note Microsoft and Apple, we are still using Imperial (our Imperial) today... Miles, Imperial pints (not US pints) etc., we had rules of thumb, and these sums were easy to calculate, once one had learned the rules.

Funnily enough, metric sums are rendered more difficult sometimes because there is a chance of misplacing that "point", or using too many, or not enough zero's. People of my age (50's), that learned the imperial system tend to have more mental arithmetic skills than younger people that use exclusively metric (apart from when they are driving or drinking (not at the same time... obviously!), who always seem to resort to a calculator.

You quoted Reagan, and that I think is very important, in essence it doesn't really matter what one uses, as long as two parties involved in a trade or an exchange know what each other is talking about, like language... The world standard is English (American), and yet most people talk to each other in thousands of different languages.

One can adopt a world standard metric system as a common, but it is not necessary to enforce it on the people that measure things in a fascistic manner, as has been repeatedly tried in the UK where people have died (maybe indirectly) for attempting to sell things in imperial, or by the scoop/handful etc..

Finally, if metric was so superior to imperial, why is it that the world ACTUALLY operates on a completely different system, namely binary, which gets cobbled together as base 8 or 16? Arguably, base 16, is far simpler to use than metric, because it is far more divisible than base 10.
