I always wonder what a better solution than capitalism is. It's not perfect, and it's pretty broken when politics and corporate interests are in bed together. However, we're seeing the ill effects of socialism (Venezuela) like starvation and I prefer the former. Furthermore, the crypto economy might be the closest example we have to "Free Market" capitalism.
