A man who has been laid off should not have to pay child support or alimony for at least a few months after he finds a new job so he can get caught up with other things. (Especially if his ex-wife is working.)
On the other hand, any guy who runs from job to job trying to outrun the law (or refuses to work at all) so he doesn't have to pay child support is a scumbag and should go to jail.
(By the way, the words "woman," "she" and "gal" can be substituted in my post as appropriate.)
