Many of them are libertarians - for whom there is no point where the group is more important than the individual
The fact that one of their go-to sources on social morality is Ayn Rand, a well known sociopath. Call me a bluff old traditionalist but I would have thought sociopaths would be the last people you should turn to to form a healthy, functioning society. Libertarianism itself isn't sociopathic but many Libertarians aren't truly Libertarian, they only hold that views as long as they think they will benefit from it. As soon as they don't, they turn on their own ideology.
Not truly Libertarian but 2 cases in point:
1 - Those predominantly on the right would be snide when the left complained about injustice and the actions of corporations. They said along the lines of "corporations can choose who they wish to serve. It's a free market, if you don't like it, don't buy their products." So what happens? People start successful boycotts and pressure campaigns to change how companies operate. Now those same people are crying "cancel culture" any time pressure is exerted on a company to change how they operate. There is no winning with these people, you literally do what they say you should and they don't like it because they are no longer secure thinking they are on top.
2 - Arguing that people should get a good education to get a better job. Then arguing that fleecing students with huge amounts of debt is worth it to get a better paying job. Then when these people get degrees, say they should be content taking any job even if it's a crap one well below what they should be getting. When they take those jobs, it's then saying they should be content with the exploitive wages and demanding more makes them entitled, if they want more they should leave and find better jobs. Now people are leaving these shitty, low paying, exploitive jobs en masse and these people are complaining about how nobody apparently wants to work any more. There is literally no winning.
Essentially it's a cover to justify ignoring social responsibilities, any problems people face must be entirely their own and completely ignores certain built in advantages. Many very wealthy so-called self made men are anything but if you look at all the help and breaks they got that many others didn't. Zuckerberg, Gates, Bezos, Musk etc all portrayed as guys who built a business from nothing but that is true for none of them. They all had financial backing and people with connections who helped them get started that they knew from before they started their businesses.
