Personally I'd rater see an increase in opportunity equality than simply focusing on income.
GE gives back in the way of jobs and innovation. How many poor families can now afford refrigerators compared to the poor of the past? Same goes for cars, TV's, phones, etc. Sure, we can make them pay more but they have the capability of moving large portions of their infrastructure to other countries (global economy) which some say would hurt our poor (and hurt ever growing government coffers....and government keeps wanting more so who pays?) more than helping our economy.
To bring overseas money home would require paying upwards of 30%, while most countries only require 0-3%. There have been plenty of CEOs in the news lately stating if the US fixed that issue they'd be more than happy to bring billions back and employ people here.
