I think the "objectively" part can be disputed, since it's very difficult to be objective about this. What are you measuring? To be truly objective you must measure outside the parameters of capitalism, otherwise you'll be measuring just what it's optimized to do (e.g. you could be measuring the ease with which one can become an entrepreneur and start a company, but why would
that be the best way to measure a socioeconomical system?).
How do you measure happiness of the population, self-fulfilment, solidarity, sustainability, etc?
Capitalism has run its course in my very subjective opinion. Hopefully there will be a successor that is more sustainable and people friendly, and hopefully it won't involve the invisible hand of the free market, state enforced monopolies, laissez faire or unsustainable consumerism.
