As a Rand fan, let me tell you: the world is not Randian. The overwhelming majority of the "capitalists" of today are not the kind I or Rand would approve it. We'd be more inclined to call them socialists than to say they are in accord with Rand's message.
If you think Rand's message is widespread then you simply have not understood it. For example Rand is sometimes accused of supporting big business. Maybe you have that misconception and think all the big businesses and their supporters are Randians. This is extremely false. Rand was very clear about how she hated many types of businessmen, and a lot of the bad guys in her books were big businessmen.
USA I suppose. But I haven't really researched Hong Kong or a few other smaller countries I've heard are good in terms of free market.
It's easy to complain about the US, and plenty of the complaints are true, but that doesn't mean the US isn't the greatest country of all time. And the US is getting better not worse -- for example if you read about the history of the railroads the amount of Government corruption and unethical business practices 100 years ago is really quite amazing and shows how far we've come. And if you go back another 100 years, then the UK was the best country, but it was really really really bad compared to the modern world -- it's hard to express how bad it was in any short statement. Gay sex was punished by hanging, there was slavery, women were property of their husbands (not 100% property, but ugh), racism was the norm, and being rich and powerful was usually about political power and achieved by methods like land grants from the Government as favors for military service; there may be quite a few bad businesses today and people rich due to crime or Government favors, but we have cut down on that stuff, and also we have far more people who earned their money as entrepreneurs, far more middle class, etc
And besides her novels she wrote books like _Capitalism: The Unknown Ideal_ where she, for example, discusses the history of the railroads, and how many of them took government money, and her objections to that, and how unfair/dumb it is that those people -- those Government suckups -- got called capitalists/industrialists and the free market gets blamed for their misdeeds.
Rand covered a lot of ground. She was big on there being objective truth -- it's not all just opinion. She was big on reason -- she wanted human civilization to make progress by people using their minds. She liked science but criticized scientists overly concerned with funding, for example, at the expense of boldly seeking potentially unpopular truths. She liked entrepreneurs because they transform the world for the better, and lead the way for progress. She liked heros who do great things, and encouraged people not to settle for mediocre lives.
She hated pseudo-intellectuals who espouse unclear, socialist, altruist/sacrificial, or subjectivist philosophy. She hated people who wanted to power over other men, and favored those who wished power only over nature. She hated collectivism; it does things like take away individual responsibility, and also sacrifice some individuals for the sake of the collective. She hated sacrifice and the altruism that advocates self-sacrifice. She wanted individual people to be able to have lives that matter if they merit it, with no one to stop them.
