You can try to fix it if you really want. Chances are you'll fail, and if you don't you will have passed onto into an abyss from which no one returns.
There are some properties of wikis in general and Wikipedia specifically that prevent it from easily being changed from without. For Wikipedia and all sites like it, the most active editors are generally NEETS and autists with a very high passion for a specific group of subjects. To that end, they'll have certain pages that they consider "their" pages, which they will watch like hawks, and undo any edit of which they don't approve. They have more time than you do, and care more about this seemingly petty thing than you do, so they'll probably win the edit war. If you win it, you'll have just replaced the other guy as the autist squatting on that page. This isn't too much of an issue for technical articles, as the biggest autist is usually correct and has sources to back him up, but they issues should be obvious for more politically oriented pages, or anything else that is easily misinterpreted. Of course, instead of doing an edit war you could try and get a mod to step in, but they'll generally favor the older autist since they probably have some established relationship. And that's where we see the problems with Wikipedia specifically, with the mods, rules, and admins. In addition to that incestuous relationship between older editors and the admins, Wikipedia has an extremely long set of rules and style manual, which was analyzed to be more complicated than the IRS tax code. What this means is that any given edit you make probably breaks at least one rule, so if need be the admins can always find some rules-based reason to undo your edit, or protect the page, or whatever. Ultimately, this means that only edits and editors approved by the admin community have any power, which is why Wikipedia articles tend to have a distinct leftist bent.
Austrian economics is an autistic enough subject that no one will care about your edits, so maybe it's worth a shot. If it doesn't work out, I'd suggest just porting the page over to Infogalactic.com.
