Perhaps there is a better unknown way to live our lives that we haven't discovered yet. How would we ever discover it if we just allow the status quo to persist? Capitalism doesn't even have tens of thousands of years of precedent like feudalism has. We unmake feudalism in much of the world, one day we will unmake Capitalism.

I bet a large portion of the population would agree that how we live our lives... is bullshit and needs to be replaced. We just don't agree with what to do next.

we should try new things until everyone's needs are met. This way of life is worthless as it only works for the 1%.
