Ayn Rand criticism often makes mockery of the grave accusations she directed at socialism and communism. Critics call her a fool and denounce her moral character, and perhaps you could say that they manage to get the upper hand in the discussion since she's already passed away and can't defend herself beyond the words she wrote/said in life and because, as I heard someone say one day "people don't learn from other people's heads," meaning that most people are unable to understand something they have not experienced themselves.
Atlas Shrugged is perhaps the most criticized of Ayn Rand's books and critics do not fear going straight on and calling her crazy for having written it. They argue - without exercising too much of an effort in crafting a logical argument - that she was simply crazy and that everything contained in the book is proof of it. Look, they say, at the bullshit she wrote. And they offer that judgment as "proof" enough.
Certainly, reading the book from the comfort of a first world country makes everything contained in it a logical fallacy. How can a modern society or a first world country fall to such depths of destruction so fast? And the rational mind of the man living comfortably with a monthly salary and some struggles just cannot believe in such a scenario.
Then comes Venezuela, which was, arguably, a very wealthy country. It was never a first world country - it had too much illiteracy, poverty and limitations on personal and economic freedoms (and corruption) to be one. But it was a wealthy country nonetheless, so wealthy that the 1980's saw Venezuelans trying to fit stuff into suitcases that had been stuffed beyond their built-in capacity in order to transport things that they had bought in pairs, since stuff in Miami was so inexpensive to the middle class that they coined the now sad and nostalgic "it's cheap, give me two (of anything)" And in spite of all that the country went down the path to destruction and failed so absolutely that now nothing works at all. There is no drought, but there are blackouts happening almost daily across the entire nation. There is net neutrality, but the internet service is the slowest in the continent and fails often. And today every single online banking platform collapsed. The country is also currently undergoing a cash shortage, meaning that people are only paid 10k VEF per day at the bank counter (a phenomenon known across Latin America as "corralito") which is not enough to buy one can of soda anywhere. This means that on this day people were unable to make transfers, which have become essential to pay for such services as taxi cabs and many other goods and services. This is so close to the scenario described by Rand in Atlas Shrugged that is almost painful to describe it. This is probably what happened in Cuba after the Castro's takeover, but without the effect of seeing technology fail so acutely as there was no Internet back then. But people (that is, middle class socialists in the US and Europe) still do not believe in her words.
In the meanwhile I am just trying to calm down. People have also become more aggressive nowadays, and I do not want to be attacked for complaining out loud. I think that if she were alive she would be laughing at all those who dismiss her so mindlessly.
