I have now learned that Ma in Little House on the Prairie is portrayed as the same sort of mother. Laura Ingalls Wilder's daughter, Rose Wilder Lane, whose contribution to Little House was somewhere between editorial assistance and writing the whole thing, was one of the leading libertarian thinkers of the 1930s.
My mother made me feel bad ("you should be grateful"*) about having toys but never actually took them away from me, so I was able to get over libertarianism.
* When I read in Stranger in a Strange Land that gratitude always includes resentment, I believed it, but I've learned that such feelings are nowhere near universal, and I figured out how not to feel that way about those I love.
Thanx to Making Light.
