Another argument for why it's good: if you're rich, you can either pay lots of money to an immigration lawyer to make sure your visa gets approved, or you could cut out the middleman and pay the government directly. Why wouldn't they just cut out the middleman?
Since congress didn't authorize this how is it legal? If it's not authorized by congress and there's no rules about where the money goes, where does it go? How is it being tracked and where will the details be published? These are the questions answered by legislation. Here, it's a black hole into a pocket with no oversight.
