Have you considered that guy with $1M won't be willing to drop like $50k (2x your net worth) on a lawyer just to squash you?

He must have possibility to earn $100k in process to do that. Well unless you really pissed him off.

If you earn $25k a year and he spends $50k in one year to take your cake. Well unless he really is your competitor that can make use of your defeat he still needs 2 years to get even. Then it probably is not easy money because there is always a risk he will not win. Maybe he can find better ways to earn more money than squashing some $25k guys.
