Simple, keep EXPANDING.
Makes it near impossible to keep a track on where the money is going.
If anyone does happen to notice that you are losing heaps of money.
Just use the Eloon defense.
It's because we are EXPANDING, profits will be coming real soon.
Can I have a BIG FAT BONUS for all the expanding I've been doing?
As I anticipated here, Mush is now publicly preparing the mindless minions by hinting at his "fall guy" replacement.
4-5 years is rather optimistic; as Tesla's financial situation crumbles, Mush will bring in some Big Name who'll probably be in the early stages of senility. It'll be great for the stock, at least temporarily. Mush will take the opportunity to cash out 1/2 his holdings and then turn his full attention to the government teat. About 12-18 months down the road, things will "unexpectedly" go wrong for "troubled automaker Tesla Motors". Mysteriously, massive debt will cripple its operations and assets will be desperately sold. Eventually, the wheezing, dying Tesla will be bought up by some sucker company and then quietly shut down, with what little IP remains sold off for pennies.
Mush gets away scot-free, revered even more as a "genius", because "look how Tesla failed without his leadership".
