put a limit on the salary, a maximum that regardless of who you're you can not exceed
stop printing rubbish paper endless, put a limit on printing, increase the value of each unit of your money and not their numbers
make it more difficult maybe to acquire fiat, so point 1 should make possible point 2 at leats in part
point 1> So you are happy to have the brightest and best of your country just up and leave, moving to another country that pays better?
point 2> Inflation/deflation of currency cannot be easily controlled as recent financial policies have demonstrated. You cannot simply dicatate what the "value of each unit of your money" buys.
point 3> Fiat drives the economy, when it dries up it all falls over. They want people spending and going ever in deeper debt to do it.
point one should be true for each country, i was talking about a system that each nation should adopt, for the globally fiat economy, not just dollar
you can contorl the value indirectly, by posing limit on some sector like the example i've proposed
if there were less money in circulation i'm sure each unit, would have a better value
