I think distribution of income is an issue in USA.
Some of the top people, like the CEO (some with private jets travels, etc paid by the company) are getting way too much money compare to the bottom people.
I am not saying people should start becoming like communist countries (of the old days), but its something that can help the bottom line alot.
There is not significant impact on lifestyle of a CEO from 2 million a year to 1,5 million, but that 500,000 million distributed to the say 1000 workers, each getting an extra $500, can make a difference to 1000 people!
On a side note, The Northern European countries (Like Denmark, Finland) have been voted best places to live & people are most happy etc, & I think the distribution of wealth have something to do with it. Even the 'low wages' people can have a decent living, education, healthcare.
