Free-market capitalism end limit is what communism's goal is, everyone is equal and filthy rich. Eventually, the capabilities of man will compound upon themselves such that anyone can get anything material at the push of a button, literally. Then, people will compete in the realm of ideas and art, things that only people can create. Things will be in such abundance of goods and ability to create that scarcity will be infinitesimal. The only limit then will be in people's imaginations of what to create. However, it will be a while before we are able to get there, even more so since government impede progress every moment it exists.
