You can only paint with a broad brush but it's not exactly hard to pick out groups that will be net recipients of relative power and wealth in various collapse scenarios.
If the financial system collapses people who own capital in whole (e.g. some tradesman with his van full of tools) and people who own "promises" of things (the contents of your 401k, bank account, etc) lose. If high level government collapses people who are associated with alternate sources of organization and administration (local government, the church) win. If local government collapses people who depended a lot on those services lose and people who already went without win.
Remember, money and political capital are convertible to each other to an extent so that complicates things as well.
So it's perfectly rational for people to root for the kind of specific tumultuous change that would benefit them.
Those who don't have a lot to lose are more interested in a chaotic phase that rolls the dice and will quickly reshuffle the social order. The rich are moving into gated communities, they're not looking forward to living in a mad max world -- they're trying to keep that world out.
To get mad max, we have to have alternative energy production and storage be cheap enough for broke people to afford. Even then, they'd need to be able to afford enough of that energy that they can spend huge amounts of it riding around looking for other people to steal from rather than spending the energy on farming and heating their homes. Raiding might work for post apocalyptic populations in Florida or South Carolina. I imagine the climate might be conducive to that sort of thing. But in a world with no energy deliveries, spending what little energy you have so frivolously would quickly doom you and your family if you live in Minnesota, Illinois, or Wisconsin for instance.
Wait until you see those who want to create a nuclear war somewhere to make an apocalypse happen so that Jesus of Nazareth can come back. Then there are also ones who believe that the nuclear apocalypse must be global for Jesus to return. Have your next shock when you discover that these people actually have politicians among them. Then another one when you discover that the last US Sect. of State himself publicly admitted to be one of those...
