Personally, I think he is wrong about cheap energy being a good thing.
................
Cramer is saying that USA could be completely energy independent in 3 years if prices hold up. But if they collapse then the drillers stop drilling and the USA continues to import oil.
I would prefer that the USA became energy independent before prices dropped below 80 @ barrel.
But the USA must become energy independent through the use of our own proven resources, not through expensive, unreliable, and unproven “alternatives”.
