No.
If, instead of trying to micro manage the economy, the government would focus on the implementation of fair and simple taxes and institute regulations designed to level the playing field for small businesses, the income inequality problem would simply go away.
Addressing the symptoms instead of the problem rarely cures the patient.
The ideal situation, of course, would be one where executives considered the effect that there personal greed has on the economy.....and thus there company's future. I once worked for a 500 million dollar Japanese manufacturer of tooling. The President of the company had a desk in the same room as the sales staff. It was a nice desk....and he was hardly ever there, but the point was made. Soon after I was hired, they held a welcome party for me. I sat right there next to the Prez. He was very proud of the fact that his salary was only about 7 times that of mine. He had been to the US dozens of times.....and he knew that Presidents of companies that size here made way more.
I am not sure how things are for Japanese CEO's now......but this dude was motivated......extremely motivated....by his desire to do well by his employees.
He was not working hard only for himself.
