Nosedive - why not hack yourself a better rating?
I get that in this future, having some sort of social media app is "mandatory" in the future - and your rating is like a criminal history check, credit report, and intelligence test all in one.
But if your rating was THAT important, why not simply hack it? Modern day government servers with top secret data can be hacked...a smart phone should be easy.
If I was the truck driver and my spouse couldnt get chemotherapy because of his rating, I'd have hacked him up to 5.1 and put it on perma-lock.
