Given the reproducibility crisis and perverse incentives of the past several decades, it may be less significant than you think. There’s no philosopher stone that turns money into impactful research. Fewer people in it for the love of the game focused on fewer problems may actually be a good thing.
What a weird argument, sorry. You're positing that those working in science aren't doing it for your decided "correct" reasons. Does this go for other industries as well? We should fire all bus drivers that aren't in it for the love of the game? Can't one still provide value?
I also think you're wrong in how this would shape incentives and the "reproducibility crisis". It certainly doesn't help that random things get axed and people can't survive in academics.
