Sounds like it's the other way around: stable currency being a natural result of less spending and debt.
Finally in a high real growth environment it is easy to raise tax revenue, reduce social services payouts, all while dropping tax rates. That makes it a lot easier to balance the budget.
You'd think so. But it hasn't happened that way in recent years. Keeping taxes low convinced politicians that they didn't have to cut spending, not that they needed to.
When somebody starts banging the "pro-growth" drum, listen carefully to make sure the tune doesn't end with "deficits don't matter."
None of this lets Romney off the hook, of course. But I'd be wary of "Club for Growth" types attempting purges when they also have things to answer for themselves.
