A lot of people are going to see some sort of causal link between them raising the salaries and the business soaring. And while I'm sure a big salary bump does bring a certain stability to those who previously had the lowest salaries in the company, that morale boost probably doesn't explain, by itslef, the big sales increase the company has seen. I'm guessing the inrush of clients was caused by the PR storm this has created, and any try to replicate their growth will be met with less excitement.
Get over it, it's been done.
The real question is, was this the original intent of the salary bump?
