How can I make sense of my child support situation?

So, my ex refuses to work, and is taking half of my takehome pay and still wants more. So if she puts me in a position where I have to choose between paying rent and eating food or paying the extra support she wants, ill pay my cheap rent in the ghetto and buy my ramen noodles. Then, what is remaining she can have. This will put me in the arrears and I will get arrested for not paying. Next, I’m fired from my job for being arrested and missing work. This means I’m unemployed, in jail, and now I have no way to pay anything to support my kids. Does anyone see anything wrong with this picture? It seems pretty clear to me. It has nothing to do with “what’s best for the kids”. If this were the case, the state would not be arresting men cutting off all support to the kids. Unbelievable. Well, hopefully I can get by until my kids are old enough to see how crazy their mother is and come live with me. Hell, she can keep the support. I can raise them just fine on my own, unlike all these co-dependent leeches that feel they are entitled to have everything handed to them while they sit on their *** contributing nothing, because why? Who knows. She can’t answer that question either, and why does she have to? Uncle Sam is on her side letting her ride the gravy train. Women with primary custody do deserve child support from the father. But you women that are like the ex I’m stating above and feel you shouldn’t have to provide any support of your own should be ashamed. You are scum and your kids will grow up and figure it out.
