Nailed it. As usual

I'm in the same boat, I am RIGHT on the line for the next tax bracket, the next time I get a raise I'm going to actually be losing MORE money... But I get it, it's to ensure the people making more contribute more so the people under the poverty line can afford at least a semblance of a life while still contributing.
