Or more: what ideology says I and my heirs deserve to continue to be wealthy and in control? Funny how we’re in a Social Darwinist moment as wealth inequality rises again. But I’m sure people couldn’t possibly be working backwards to justify their position. Certainly the wealthy, who fund research, wouldn’t twist a science as pure as economics like they did the soft science biology.
Meanwhile extreme poverty levels have been steadily diminishing and quality-of-life broadly improving. But you're concerned with some people having more money. That is to say, equality of outcome. No safety net would ever be enough for communist ideologues, because results and well-being don't matter. Only ideology, and punishment.
There's a reason would-be socialist states have back-tracked from central control of economy and allowed competition (Lenin did this so quickly in spite of his zeal it would make your head spin). They kept the authoritarianism though. Once those tendrils get in, they're tough to get out. Only a few countries shed that in the 20th century, one of them being South Korea; places that embraced Liberalism, because they had the good fortune to have leaders with sense.
Liberty qua Liberalism is good, and the checks-and-balances are meant to evolve over time. The alternatives are abject failures, and you'll propose nothing that hasn't been one.
What does that have to do with whether or not economists are serving a useful role day-to-day? For instance, most economists now agree most economists were wrong about the way to respond to 2008, and the austerity measures actually caused more pain for most people. Seems like exactly the sort of recent failure which should make us question their current advice. Especially if the current advice benefits the folks paying their salary.
Regardless, I stand by my derogatory comments about social Darwinists.
