"[edit] Famine Follies
The Irish Potato Famine of 1845-49 led to the building of several follies. The society of the day held that laissez faire, not a welfare state, was the appropriate form of civil management. The concept of a welfare state was a century away, and at that time reward without labor, even to those in need, was seen as misguided. However, to hire the needy for work on useful projects would deprive existing workers of their jobs. Thus, construction projects termed "famine follies" came to be built. These include: roads in the middle of nowhere, between two seemingly random points; screen and estate walls; piers in the middle of bogs; etc. [Howley, James. 1993.
