Best interest of the children, Missouri child support

I would just like to start by stating all parents do have a responsibility to the security of their children. That being said, I have been divorced and paying child support for 6+ years now, so I feel I can speak fairly intelligently on the subject.
When a person has been issued a court order to pay child support, at least in Missouri, they are made to feel like a criminal under the scrutiny of the "authorities" appointed to collect the said support. They will do whatever they are legally allowed to do to collect from you, even if it bankrupts you, without care or mercy. After jumping through their hoops and waiting long periods of time to speak to one of these "authorities" through one of their approved avenues of contact, you are treated like you are bothering them. They will send you a piece of mail stating they are acting in accordance with some law allowing them to do so. Just because you can doesn't mean you should. No two situations are the same, so how can they used standardized methods to set and collect support amounts? It should also be noted, the amount of funding these organizations get from the government is based on the amount of "support" they collect annually, so it is in their best interest not only to inflate the support amounts set, but to collect all they can, however they can. They garnish wages, put liens on property, revoke licenses, and jail people who don't or even can't meet the set amounts. If you go to the Missouri Child Support Enforcement web site, you can see a graph showing the amount of support collected year to year and the exponential increase over the past few years. It is almost like they are bragging. In a time when so many are out of work, losing their houses, and stuck in this recession, I would think they would ease up and help out the citizens of the state, but the amounts in arrears just keeps adding up and they threaten jail,license revocation, or worse. There is a big "not my problem" attitude in the government.
How is this in the best interest of the children? My children watched me go through a chapter 13 and then a chapter 7 bankruptcy. How is this in the best interest of the children? They see me continue to struggle day to day financially. How is this in their best interest? One of the first few sentences on any court document pertaining to support modification, custody, or visitation(which is another sore spot for me. I am a parent, not a visitor! but that's another blog) or anything else that involves the children is "We feel it is in the best interest of the children...".
How is any of this in the best interest of the children? Again, just because they can, doesn't mean they should. To add insult to injury, the state now charges a yearly fee for their "services" to the payer of support. The payer is also responsible for ALL taxes on this money. Where does it end?
In the interest of not just bitching but offering a solution, I offer this. You take the monthly cost of running a normal house hold, (say $1000), divide that number by the number of people living there,(say 5)=$200 per person, multiply that number by the number of supported children,(say 2)=$400, each parent being responsible for 50% of that amount =$200 per month. Any outside costs like sports, glasses, doctors, etc. would be split 50/50. To me, this is the truly fair solution. I feel THIS is in the best interest of the children. All you deadbeats need to step up and take care of your kids!
