Anyone can "contribute" to discussions on anything from the budget of the DoD to health care without having the slightest clue how anything actually works. All you have to do is instead of having to deal with those cumbersome details you just talk about "money" and suddenly everybody is free to join the discussion with great enthusiasm and unhindered by constraints of missing information or subject knowledge.
That's also why a lot of "solutions" to any problem work like this:
Problem => Money => Solution
Problem => Magic => Solution
