Have you ever wondered what the Empire's planet-destroying superlaser did to its finances? The website Overthinking It explores how the Death Star project would have affected the economics of the Imperial war machine. In the post, financial analysts describe the benefits and consequences of blowing up planets right and left.
Here's an example from an analyst named Lee:
"Doesnít the Empire take a huge economic loss from the lost productivity of an entire planet? They were presumably paying taxes and providing resources to the rest of the Empire. Presumably the loss of that planetís output would have to be made up by increased output from other planets that were either slacking in productivity due to rebellion or threatening to rebel and withdraw from the Empire altogether. It doesnít seem to make good economic sense."
Analyst Fenzel adds this:
"So, say the destruction of Alderaan is a shock that brings on a galactic recession that lasts a couple of years. We would be screaming about it, but what does that really mean to the Emperor? Weíve already established he doesnít even really care about governing his Empire effectively. The larger questions of whether to build a Death Star or to reinvest in more ships and personnel makes the loss of Alderaan pretty insignificant to him even if it does affect a bunch of peopleís livelihoods who didnít live there. And then that all, in turn, is insignificant next to the power of the Dark Side."
