The constant reference to "beancounters" as a threat to airline safety is a bit fanciful. It's not the accountants' fault if safety standards are insufficient.
If there are failings (the evidence isn't convincing) then the problem is regulation and enforcement. From food to finance, we have seen constant pressure on funding to regulators during the past few decades (not to mention the busting of unions). It wasn't beancounters who did this — it was right-wing ideologues.
