Very few of us like to be confronted with unpleasant choices. If we are, we will tend to delay a decision. And if forced to make one, we will likely opt for the choice that, in our minds at least, seems less disruptive upfront — even if we know it is likely to involve discomfort down the road.

This simple human analogy is critical in understanding why Europe’s increasingly ugly debt crisis refuses to go away. It sheds light on the choices made up to now; and it speaks to why an increasingly incoherent policy response will likely end up in tears for Greece and potentially other European economies and institutions.

Let us wind the clock back to just over a year ago when Europe first bailed out Greece, a country no longer able to pay its bills. Together with two monetary institutions — the European Central Bank and the International Monetary Fund — European politicians faced unpleasant choices and had to respond. But rather than decisively addressing the problem, they essentially opted to kick the can down the road.

There were, and still are two main reasons for Greece’s predicament: The country borrowed way too much; and it failed to grow its economy on a sustained basis. This lethal combination was amplified by weak public administration.

Yet the rescue of Greece involved making new loans to the country and was asking for a very ambitious fiscal adjustment effort. Neither the size of the debt nor growth reinvigoration were properly addressed.
