not sure what type of Point you're trying to make there but I have no ex-wife and my kids are grown.

She wants to live a lavish life without having to support her children so why not take custody and let the money maker support her

Duly noted taken from someone by the name of token commenter. From the tone of your comment I would take it that you must be 18.

it's obvious his ex wife wants custody so she can get child support payments from her successful ex-husband.
