For the record though... the Gini coefficent and wage gaps are pretty much always going to grow.
The only times they go down, are times of economic hardship like the ones we have now.
There is a pretty straightfoward reason for this...
Economic growth is largely created by the rich investing money to make buisnesses, factories and products....
or it's created by the people who have a great idea and create completely new products... these people then become rich.
There really isn't any way you can stop it... even with progressive taxation because if you tax enough to where you can stop it, well then people just stop investing because now they aren't getting any benefit from investing.
Even huge estate taxes leads to nothing since that money just goes to the government who then spends that money on projects that go to rich peoples companies.
The real question is... does it matter?
Money isn't a zero sum game afterall. 10% of wealth now can buy more then like, 30% of wealth 100 years ago.
As long as value is being added and most people can afford more now then they could 10 years ago, who cares?
I'd rather be able to buy three videogames and my neighbor be able to buy 2 cars... rather then me buy two videogame and him buy 1 car.
Really, the only way to lower the gini coefficent during times of prospeirty is to convince the rich to buy cheap, stupid things that are cheap to make.... or change society to be more charitable so that said money instead of going to rich buisnesses by the government.... it goes to charities that work to give to the poor in more "real" ways. Even things like foodstamps don't really increase the gap.
Maybe we could convince the rich to buy poor peoples children. Like I dunno for food or something. (This is a reference to something by the way... an ironic use and refrence... but it's basically true.)
Edit: Ooooh good Idea.... get the rich addicted to games like TF2.
It sells items and valve gives the creators a cut, the creators just being every day people who know how to model stuff.
