100% Base Comp?

I recently finished reading a book called Drive by Daniel Pink. The entire premise is about how the science of motivation is different how businesses try to motivate their employees. How motivations tactics that are "if then" , example being if I sell x amount I receive x amount in my bonus, are actually not motivating in the long run. His argument with money is once you are at a threshold, money has not factor on motivation. 

With every IC role having a % base % commision, has anyone heard of a 100% base role in sales that's IC? How does the team perform? 

also questions for the top reps, what motivates you to continue killing it when you are probably making an amount of money that you are happy with?

Daniel Pink also has books on Sales and is the instructor in MasterClass for sales so I feel like he has some credibility?

I am 25 with no big expenses so once I get to 100k it's truly not the most motivating thing to get to 110k or more since I can pay for everything I need and hit my investment goals. I am sure if you have a family or a house it's different. another thought of taking away the commision leads to less sketchy sales tactics.
