In an open economy, you will never know what is out there on the leading developmental edge of this or that industry. But the reality behind the miracles is the same: Someone innovates something useful, makes money from it, and re-innovates, or someone else trumps their innovation. Most of the time, no one notices. All it does is create jobs, wealth and well-being. But without this system running in the background, without the year-over-year progress embedded in these capitalist innovations, those trapped miners would be dead.
If only everyone who was mortally confined to their place of work had the benefit of more capitalism!
