Why do CSA want more money, the more you earn?

csa takes 15% of NPC’s income. it sounds to me that not every children are worth the same. right? why would a father who earns a considerable life through hard work shall pay more than a father who earns a less well off life, but still through hard work and vice versa? (i mean, does a child needs a levis every week, an iphone and a meal at the savoy or cantine’s price remain the same for rich and poor???????

why shall bonuses be assessed on their calculations, when obviously they can not be properly estimated? i am a French man, living and working in the UK as the rest of you lads, and can not see my child because his mother took him to Russia where she is from, and still have to pay the csa:> by the way, she receive the full amount since is working….in Russia:> csa said that’s ok. Great Britain used to be seen as THE place where things were great and equal. Now, what kind of country is it to threat his men so terribly???? By the way, i just realise that if you can prove that you are actually not the biological father, they still will not give you back your hard money because the ex has obviously spent it:>
