Tax dollars, invested into an institution that creates a public good, that is then made available to the public, where any entrepreneur can recycle it for profit and create more tax revenue. Beautiful fair capitalism at its finest!
In all these cases Royal monopoly power was curtailed, allowing more people the opportunity to profit from their efforts. And there were relative economic booms as a result. But we strangle growth when we reinforce monopoly power, or when we reinforce laws that keep money in the hands of people that didn’t earn it (and also strengthen the political power that money alone has).
When monopoly power is a temporary reward for innovators, it works. Anyone that seeks to extend the time limits of monopoly powers beyond the sweet spot is trying to restore one of those unfair capital systems that kill economic development. They generally don’t care because for them, it is about enriching themselves whatever the cost to society.
