I can get behind the idea of wealth redistribution. I'm making decent money (enough to eat out in Seattle) so I usually tip 15% normally and 20% if I've been a nuisance with special requests, etc.
The idea of knowing who my money goes to is important. If I can interact with waitstaff and tip them for helping me through the dinner transaction, I feel like it's a bargain. On the other hand the tip jars seem like a donation to management and not the workers. On the POS screen, it's always 'no tip' for me with cash on the table.
Reducing for terrible service I understand, but what about non-existent service? Someone only came by to refill a drink after I flagged them down and I had to chase down my check from some other person. Is that terrible service? Those aren't kitchen mistakes and I'm not some feudal lord that demands my servants' full attention - but that's literally their job. Would you tip 10% in that situation?
