Just a guess - but their funding is probably tied to the number of busts they make, so they're probably encouraged to increase the number of busts by their managers
Nope; any kind of quota or reward system based on arrests in constitutionally illegal in the US. That doesn't mean it doesn't happen - it's more or less ubiquitous in metropolitan PDs since the fetishisation of crime states - but much harder to get away with in a Federal agency.
The major reason for the shift in the LEO (Law Enforcement) branch of the ranger service is the huge number of military veterans. Because they are given (by law) preferential consideration for federal and law enforcement employment it's now almost impossible for anyone coming from a more traditional ranger background to make a long term career; you're just tied in to seasonal contracts at different 'units' (parks to you and me) with very little hope of permanent employment.
This has led to a noticeable shift in attitudes.
The other issue, to be fair, is the overwhelming visitor numbers now in Yosemite Valley during the summer. The attitude in less popular Parks (e.g. Joshua Tree) is a little more easy-going, but still the 'Tool-factor' is evident at times. Sometimes justified, sometimes not.

Depends very much on the Police Department. LAPD are pretty good now since they brought in Bill Bratton to deal with the Rodney King and Rampart fallout. LA County Sheriff's Dept though, are truly the scum of the Earth - greedy violent criminals in uniform, headed by a religious conservative with a personal 'moral' agenda.
And that sums upload enforcement in the US, including the current iteration of the Park Service. Local and internal political shenanigans and the lack of any kind of oversight for regional police organisations means that it really is just the luck of the draw whether the law enforcement agency you're dealing with has a culture of 'Protecting and Serving' itself or the public.
