Most people target 4% withdrawals if you want to live off the nest egg in perpituity, which in this case, would be $12k/year. Less safe investments would earn you a higher return at the risk of sacrificing principal.
Edit: Something important to note is that you can live very well in other countries for what would be considered the poverty floor in the US. For $2k/month, I can pay for a very nice luxury apartment, day camp, and a nanny for my kids in parts of South America.
