This is the end result of the 'old boy network', where the aged rise to the top on the basis of how many ticks they have groomed off the fur of the silverback's fur, in the USA/Japan, with no fur, it is the ass licks ledger that counts.
Sadly, this is fully operational in the USA military, where billions are spent on old weaponry whose life in a modern war will be measured in minutes when they meet modern drones. (by drones, I mean land based drone attack tanks etc, with costs only 5-10% of the cost of the manned equivalents, air based drones, surface water drones as well as submarine drones)
We see China and Russia unfettered by this old boy network that are allowing their brains unfettered freedom to make modern stuff.
This has happened before, when the blitzkrieg fought horse drawn gun carts at the start of WW2, when allied armies in Europe were prime examples of the old
boy network.
Why do we have it? We have a bribery and feedback mechanism in Congress that quantifies bribery and ass licking to perfection. An elected representative HAS NO SECRET BALLOT!!.
We can all see how he votes, as can all the bribers, who can call him to account.
We say this exists to allow the voters to see that there rep did their bidding YADA-YADA-YADA - we all know it allow the bribery effectiveness to be watched and measured, so you can threaten to cut them off if they do not dance to the briber's tune.
RANT/ How to get a better way? Empower all, with online voting of all eligible voters, in the style of the original Greek democracy. Pay people for their votes, hold back tax refunds for people who do not vote etc. This needs to be fine tuned.
Chance of success = zero, as all the well bribed elected officials do not want their gravy train to end. /RANT
