Is a one world govorment an asset or a liability to its people?

Ask Hitler....or the Romans....For if my history is right...That is what they wanted

Liability. There would still have to be regional government. And there would still be regions that want to do things their own way. Besides, it's been tried before. It always crumbles eventually into chaos.

Neither - it is already getting abused.
While it is not yet fully developed, but in the beginning only.
It always happens LIKE THAT with simply anything in this World - much looks like the humans are incapable of having proper normal society and lives.

Depends who is running it...

A great liability.
The more decentralised a government is, the more details will be important and therefore each individual. Even a better form would be top down: citizens decide what governments should or should not do (that's different from elected pyramid shape). Of course, cooperation between different governments is a good thing.

The less power is concentrated,..the greater is democracy...Education and awareness then becomes paramount...The more people relinquish their responsibilities to government beauracracies(?),...then the more we all get exploited...Its good for some utilities to be govt.run...along with essential services (welfare/health/education etc.)....but its always best to keep the power base spread across the populace...So that each person has greater access,..and a say in what goes on...Better to have many 'little brothers (yes and sisters),..rather than one big brother..Power corrupts...Just like money,..it is best shared,..not horded.

Liabilty.. i think no man in the world has got the power to rule the world! Each country has its own set of problems that can be understood and tackled better by someone from their own land.. So world govt is feasible only if all people follow same culture and brought in same way which is highly unlikely.. So present cooperation betn countries is the best soln we have!

One world government is a hideous idea. There is no room for individual rights and freedoms. If you disagree with a decision of a world government, who would you complain to?

There are assets and liabilities which must be weighed. In my opinion, it will be inevitable at some date in the relatively near future. Do I like the idea? No. The idealists believe that it would rid us of our differences. Like Marx, they don't take into account humankind and look at things as if it would be an ideal world made up of ideal people. I hope I don't live to see it.
