Reining in the reign of rain

The wannabe copy editor at casa Monzeglio, the Divine Mrs. M took umbrage the other day when our local paper used rein instead of reign in a news story.  I doubt one in one hundred of the Press-Republican's readers (If it has that many) noticed the mistake, but as my better half opined it is a symptom of the times.   Many things can derail a democracy, but a decline in literacy is a major indicator that something is wrong.  Of course the very existence of a tRump presidency is a tell tale, but the inability of people to grasp proper grammar and usage is a serious problem, despite what many people would describe as elitist attitudes.
