Hacker shacks can definitely pay off! They aren't the only way to skip the progression. In fact, I'm trying to build in multiple "game-breaking" combos of buildings.
My current record is a Corp building making 11k in one night! I had to nerf the Security Forces in the most recent update because they were just too powerful. A certain amount of "too powerful" is encouraged, but that building made it too easy. The new update reduces their area of effect, which should play a little better.
