If everyone on earth is given a million dollars each, will that end poverty?

I GUESS IT COULD

That wouldn't change the amount of goods and services in the world. But there would be a WHOLE LOT MORE DOLLARS chasing those goods and services.

No it would probably start WW3

Nope. Everything will increase in value.

Maybe temporarily, but it's not that simple.

What is in place to prevent the costs of goods and services from skyrocketing should every have suddenly have a surplus in funds?

What about the multitudes of services provided daily? Will people still see the need to work and provide necessary services? From Medical to Agriculture to Engineering, Trades and everywhere inbetween. 

What about taxes?

What about printing costs? Money isn't free to print..

What does it mean for the stock market?

How will it effect exchange rates etc? 

Is there a long-term plan in place?

There's a lot to be considered here.

No.  The cost of housing rises whenever people have access to more money.

no the greedy will raise all their prices

No, because the poor people will spend it too fast, and be right back at being poor. A million dollars does not buy what it use to buy.

1 million dollars will make you rich.
