I'm no fan of retroactive cuts but there's a lesson to be learned here. If the industry self-regulated itself we wouldn't see these steep subsidy dropoffs. Why has the industry chosen short term gains over sustainable policy? Hmmm... Gonna have to go with greed on that one.
The industry should look at itself in the mirror and eliminate those participants who aren't in the game for the long haul. The players that are left will me much more interested in balanced long-term policies.
