Nope.  China and India have millions of very smart people but the number of rich and poor alike wanting to leave those countries, and not many wanting to move there, are signs of those nations having collapsed.

There's other qualities that are also needed to make a great nation besides intelligent and hard working people.  You need people who are willing to fight income inequality, fight lax environmental and human rights laws, and people who have enough pride and self respect not to let themselves be used by those in power, even when their immediate, short term financial interest would be to just shut up and get paid slightly higher than your neighbour but less in one year than your boss earns in a day.
