Largest employers (head count) is a very poor metric to measure diversity of an economy, as some industries by their nature have more employees.
Say what?
Graph #1 - Number of Service jobs in America:
Graph #2: Number of High Paid Manufacturing jobs..
In 1980, less than 24% of all U.S. jobs were low income.
Today 41% of all U.S. jobs are low income.
Still think it is a poor indicator of the economy??
