The Secrets of Star Wars: the Architecture of the Death Star

Many Star Wars fans have wondered over the past years about the interior of the Death Stars. Until we build a "Death Star", we will never truly know what it looks like on the inside. But we can make very accurate guesses. One way to do this is to look at the 2008 Lego Death Star. We already know how the "Superlaser" of the Death Star works. So we don't really need to look there as much as the rest of the Death Star. We also know that the Death Star has at least one trash compactor, and at least one prison block on each floor, as well as hundreds or even thousands of tractor beams. Plus millions of cannons, hundreds of tie fighters, and 15 million people. These are huge numbers. And now you must be thinking "How much does it take to keep these people alive"? Luckily, we don't have to do any CRAZY calculations, because people have figured that out already: The cost of the Death Star is $350 billion! Not even Bill Gates has that much money. And don't forget these millions of people are living in outer space! The Empire has to build recreational areas, Anti-Gravity Machines, and much more to keep their people sane. Given these facts, to build the Death Star is possible, but it would be the greatest feat ever taken on by humanity. It would cost so much that every nation would have to pool 0.5% of its total annual income. We will have reached our pinnacle, once we have built a Death Star.
There is a lucrative way to build a Death Star: Some "Super Star Destroyers", mile-long ships that house storm troopers, can fit entire cities on them. These would cost about anywhere from 3 billion dollars to 25 billion dollars. To be honest, I don't think the people of the earth should use Death Stars for blowing up planets. That would cause the ultimate World War. Instead, we should use these weapons as tools. We can solve poverty by housing the homeless on Star Destroyers, for example. So if we build these Star Destroyers and Death Stars, then figure out how to use them for good, we will indeed reach our "pinnacle".
