I saw this video yesterday (link in the bottom) that made me realize two interesting points:

1) Capitalism is above all a mindset.

- Before capitalism, we would have a cycle like this: product -> money -> product

meaning, we would work making useful products (food, chairs, clothes, ...), sell the production we don't use, and then use the money to buy other products that we need.

Money was just an intermediary to help us getting the basic items we need to live.

- Capitalism changed the cycle to this: money -> product -> + money

We invest money, making products (businesses) with the goal of making more money. Money (or capital) became an end in itself.

2) Daily life decisions we make can favor one of the two cycles above.

If we buy a coffee from the local shop (not a chain), our money is going to be spent in the owners life needs (bills, holidays, etc).

The owner does not necessarilly expect the returns of the shop to constantly grow.

On the other hand, if we buy a coffee from starbucks, the capital is going to be used to invest in other stores, machines and assets. 

It's not just going to fulfill someones needs, its going to be used to make more and more money. 

Check out the video (its quite cool): https://www.youtube.com/watch?v=f3f8ZGZ75zg
