Plenty of examples of Dads that work hard in Illinois, have 50/50 or a little less custody of their children, and have to pay a large set percentage of their net income to an ex-wife that makes many times more than them. There is no way that situations like that can be seen as fair and equitable.
And that is where I was almost at in Missouri; 50/50 with a decent job (but still underemployed caused by a manipulative relocation on her part prior to divorce) and having to pay a substantial amount of my monthly income to someone that makes nearly 1/4 million per year. Made no sense at all to me. However, the reverse in which she would have paid me made more sense. In the end, no child support changes hands.
