In different countries at different times, very different "systems" can exist. Still they all can be called capitalistic. One can imagine society where single person owns 99.9999% of wealth. It is where we are going to. No wonder that not all are happy. These bags with money have no plans to invest so that society, infrastructure, people could benefit. They just like to watch how numbers on their accounts are growing. In "normal" systems, the richest men DO have a big influence, but this very influence has a lot to add to nation's power.
