It turns out the Greek government is proposing that a wall be built on the Greek-Turkish border to curb the waves of illegal immigration that are adding to the country's problems.

I propose the following:
1) Immediately demote policymakers who proposed this concept as a good idea, give them a map and tell them to spend the extra time studying
2) Use the money to improve the infrastructure so that a process can deal with the problem, not put a brick band-aid on it.
