Oh, the Genius of Jack Welch is simple. Lie to investors while dismantling the company you're in charge of. Use the profits from selling off the dismantled bits to cook the books so it looks like you're becoming more profitable, this will get you lots of bonuses and you'll become super rich, then just walk away before anyone figures out your bullshit. Sure you've destroyed hundreds of thousands of jobs, and ruined one of the most profitable companies in the world, but you're rich now, so fuck it. Pure genius.

Since Welch climbed the corporate ladder over the years, this says a lot about the rot predating him as well.
