This is a bazillion times worse than cash in an envelope, because it's straightforward larceny of public resources, papered over with some thin PR nonsense about "efficiency".
This current government isn't even pretending to do anything else. There have been so many no-bid contracts for "PPE supply" handed out to cronies with no PPE experience - and no PPE delivered, while lethal shortages continue - that there are are now formal legal challenges working their way through the courts.
The current government in the UK is uniquely poor compared to every UK government that has come before it. The situation there does not extend to "western nations" in general - just those run by incompetent/malignant (take your pick) populists.
We don't eliminate corruption as we 'advance', but instead we just keep abstracting it away until the less observant don't see it as corruption but instead some form of 'networking'.
So cash in hand is a bazillion times worse than a board seat.
