Traditionally, the division between conservatives and liberals has been over the role and size of the welfare state: liberals think that the government should play a large role in sanding off the market economy’s rough edges, conservatives believe that time and chance happen to us all, and that’s that.
But both sides, I thought, agreed that the government should provide public goods — goods that are nonrival (they benefit everyone) and nonexcludable (there’s no way to restrict the benefits to people who pay.) The classic examples are things like lighthouses and national defense, but there are many others. For example, knowing when a volcano is likely to erupt can save many lives; but there’s no private incentive to spend money on monitoring, since even people who didn’t contribute to maintaining the monitoring system can still benefit from the warning. So that’s the sort of activity that should be undertaken by government.
So what did Bobby Jindal choose to ridicule in this response to Obama last night? Volcano monitoring, of course.
On the heels of that attack he also takes aim at the Obama Administration's half-ass crutch for banks:
Ben Bernanke’s testimony over the past two days gives us our best clue yet about where the administration and the Fed are going with bank rescue. And the answer seems to be … nowhere ....
As long as capital injections are seen as a way to bail out the people who got us into this mess (which they are as long as the banks haven’t been put into receivership), the political system won’t, repeat, won’t be willing to come up with enough money to make the system healthy again. At most we’ll get a slow intravenous drip that’s enough to keep the banks shambling along.
