Why Change from Republic to Monarchy?

[anweRU]

The problem is, republic and absolute monarchy BOTH get the same industrialization penalty (more or less). CM gets none. That doesn't make sense. I'm pretty sure GB had as much worker unrest as the USA and continental Europe in the 18th & 19th centuries.

I suppose they could point out to the late-20th century French, Italians and Greeks (among a few others) as examples of industrial unrest in republics.
