AynRand ended up taking social security and medicare [ or their equivalents] in her later years.
Ayn rand has become a symbol of hypocrisy in most circles these days. She founded a cult of personality based on rejecting cults of personality.
She's also pretty unpopular with feminist groups for her depictions of erotic rape. She had some pretty messed up ideas about sex, with became more clear in her later life as she got personally involved with some of her disciples in weird power-dynamic love triangles.
Also hugely unpopular with minority groups, for the ways in which she advocated that the oppressed poor deserved to be oppressed. She seems to have genuinely hated the Native Americans in particular, for their "share the earth" philosophy and for failing to embrace western cutthroat capitalism even after it destroyed them.
Unsurprisingly, she's hugely popular in the Trump whitehouse. Trump has personally cited The Fountainhead as his favorite book. Like five of his cabinet members (Tillerson, Pompeo, etc) have quoted Rand as their defining literary influence, and her policies of unrestrained personal aggrandizement at the expense of all others explains a lot about the way Trump does business, even if it does seem somewhat counterproductive to the exercise of government.
So her books, though childish to most modern readers, still hold sway over people in power. Even the worst ideas have to be taken seriously when the POTUS talks about them. See: wall, travel ban, children in cages, grab her by the pussy, very fine people, etc.
