Step 1: Steal nuclear weapon.
Step 2: Detonate in North Korea (Best Korea), or whatever country most likely to overact and kick of the nuclear holocaust.
Step 3: Apocalypse!
Step 4: Remake world in your image. People live in treehouses, and beetles are used for currency. The shinier your beetle is, the more it's worth.
Step 5: Start a illegal beetle-polishing operation. Buy up all the community's least shiny beetles with beetles of slightly higher value, or just trade for grubs and trinkets. Polish their carapaces with tree sap and waxy leaves. Invest these beetles into the speculative carapace market at higher value.
step 6: You are now rich with beetles. Do what you will.
