Should Bankers salaries be raised to attract new talent

Article From Journal.ie concerning increasing bankers salaries
In my opinion bankers salaries in Ireland should not only be capped but actually slashed. I may be wrong but most of the positions in Irish Banks are actually filled from within the bank itself. So in effect you are not attracting the top candidates. You are in fact just awarding higher salaries to people who would have got the jobs anyway. The entry level for banks in Ireland are at the clerical level and then employees work their way up the career ladder within the bank. So really is the banking sector in Ireland a closed shop. The circle of available employees at higher levels are likely to come from within the bank or at most from another Irish bank. So how can it be said that the higher salaries are attracting a higher caliber of staff when in fact the staff came from the Irish banking system anyway.
It might be argued that the higher salaries retains higher caliber staff but really where would they go to anyway. All that happens in Ireland is that staff would transfer between banks so the talent pool is not expanded. Irish banks would find it difficult to compete with foreign banks anyway for the few really exceptional staff who most likely are so career focused they would be heading abroad anyway.
I would suspect that for the higher management levels that the employees hired by banks are even more restricted to people who came from certain schools and social circles. I believe Shane Ross highlighted this in one of this books on the Irish banking system.
