The elite will be just fine - don't you worry about them now. That is, until the judgment of course. Meantime, they're already making preparations for the apocalypse, which they think they'll escape coz they have money and power. And as everybody knows, money buys you whatever you want - even a way out of the coming judgment, right? As if God can be bribed with His own property. Completely delusional.
As for any new oil discoveries in Israel, I somehow doubt it. If they're there, they would have been discovered by now. Israel's only hope is a pre-judgment mass conversion to the Messiah they rejected first time round, à la olive tree of Rom. 11.
