Correct me if I'm wrong, but in Europe there are some countries where child support payments are set according to the lifestyle the child-mother are accustomed to, and in others a percentage of the male's income.
I knew a guy that had his own successful business and got divorced. He had to pay child support according to the lifestyle the child was accustomed to pre-frivorce. Then the business failed and he became a normal salaried employee. The court refused to change his child support payments, so he moved to a different country (still in EU) where child support is determined based on percentage of income, which in his case is now pretty low. He had to go to court in the new country to make this happen, though.
