W/P = MP?

Bankers are, apparently, being rewarded generously for their fine performance in recent years:

In 2008, salaries of the top 10 banks reached $75 billion (up from $31 billion in 1999), while cash dividends to shareholders were only $17.5 billion. Management took 4.3 times more than shareholders at a time when shareholders were injecting capital and government was guaranteeing deposits.

If people were really compensated according to the value they create, wouldn't bank managers would owe us money?
