What are some realistic and creative ways to reduce wealth inequality?

I would love to hear some creative and realistic thoughts around reducing this social issue which is a rapidly increasing, world wide issue. If anyone is well versed around topics such as this, stating your political ideology/perspective/basis of your ideas would be a great help so that I am able to further research the good idea's!

The primary focus will be on reducing wealth inequality as by doing this, social cohesion will increase. Despite this, I do hope to develop a small scale plan to increase social cohesion as well to strengthen the assignment.
