India and Brazil overtook it thanks to massive growth. That's not a problem for Italy directly. The US has changed from 29% of the world economy to 24% over the same period.

Relative numbers are slightly more concerning though.

Since 1999, Italy's gone from 3.8% of the economy to 2.3%, a much larger drop than the U.S.
