Conservatives don't ask for more government involvement to manipulate the market.
You don’t speak for conservatives. Nor do you speak for anyone with real connections in the oil trade.
Preserving American oil/gas production is in the interest of national security. A foreign power (Saudi Arabia) is waging a price war. It is not a natural occurrence of market economics but a deliberate strategy to shape a vital market to their advantage and our detriment. A non-shooting war but one that could still have a devastating impact on American jobs and our economy.
I consider myself a conservative but one of the natural functions of govt is to defend us against foreign attack. I think import tariffs to protect our domestic oil/gas industry is absolutely called for in this case, which is why Obama won’t do it.
