Scientists don't (typically) run journals, publishing companies do. Scientists just write and review papers for free, and they have to pay for access. That's hardly "running" anything.

Scientists do tend to decide who gets grants, but most people I know don't consider those decisions to be too bad per se. The main problem is that the lack of funds causes grant award rates to be so low that very good candidates can be left out, plus when resources are so low the random factors inherent to assessment become too important (with a 50% acceptance rate, a very good project may score lower than it would deserve but still get in, while with a 10% acceptance rate if a single panel member dislikes your project you are likely out).

Not saying that the scientific community doesn't have its share of the blame for its problems, but an important part of the blame is political as well. And scientists are too busy trying to survive in an extremely competitive environment to try and change things by themselves. Honestly I think most of science's problems would be solved just by allocating (significantly) more money to science. Then maybe we would actually worry about doing good science and incentivizing others to do so, rather than about finishing our reviews ASAP so we have time to hastily write another journal article that we need to score points for grants/tenure and not bite the dust. A degree of competitiveness is good, but competitiveness in science is now absolutely over the top and creating all kinds of evil incentives.
