Maybe so, but it is highly praised and recommended by experts.
However, I would fault the central Austrian economic premise even if I'd never looked at a bit of macroeconomics. I would do so based on what I understand about human potential.
In the raw world of nature, it is survival of the fittest. Competition helps decide whose genes are passed on, and between predator and prey, who survives. Humanity adds consciousness to the mix, and that has the potential to lift us out of being mere mindless followers of our animal heritage, and into realm of love, cooperation, and concern for all fellow human beings.
The infant mind starts life self-centered. Good influences growing up can teach a person not only is one not the only and most important person on the planet, but that there is great personal satisfaction in working for the good of humanity. When done correctly, working for the good of humanity makes everyone richer because it creates more productive and contributing individuals and diminishes the strife that arises from people not getting their needs met.
Yet in this world are plenty who never quite get past being self-absorbed; often they are in continuous struggle with society pressing them to be concerned for humanity, and their own urges to think only of themselves. Then along the way they might, for example, read Ayn Rand and find support for their selfish urges, find a political party and economic theory that support it too, and at last find relief from the internal struggle to care about anyone but themselves.
The idea that wealth is to be decided by competition, along with
no principles for fairly distributing the wealth accumulated to all participants (or helping
willing nonparticipants learn how to participate), serves the selfish well. Learning how to win competitions is often mastered best by some, who then acquire the means to win even better, until at the top are a relative few controlling and possessing far more than they need or deserve.
One can bury the idea of letting competition decide everything with a mountain of economic esoterics, or one can call it "freedom" or liberty (i.e., a market free/liberated from regulation so competition can decide), but none of that helps the central principle work any differently than it ever has.
