Sure it's changing things in the real world. And in a positive way. You are providing funds for companies to exist. Companies that pay some of the people, and provide services for other people. You also get a share of the profits. Certainly, this can be abused, but at the fundamental level, it's a good thing to have businesses that provide value. I like being able to go buy a nice computer when I want one, or going and getting some fast (or slow) food. I also like googling things. All these things are (often) supported by stocks.
