Logistics do pay on par with banking and insurance. I think you are mixing up logistics with the transportation sector/companies. As a logistics solution provider provides end-to-end solutions including documentation, warehousing, transportation, invoicing, etc., it becomes a supply chain management company in itself.
If you go through the entire history of all three sectors, you would come to know that while banking and insurance were basically managed by the government/PSUs, the transportation sector was managed by the private sector.
Furthermore, with the banking and insurance sector, you need to have that extra knowledge, so mostly graduates/postgraduates [and now for insurance, you require special qualifications]. Qualified people with the required qualifications are in shortage. So the law of economics plays a role here in terms of demand, supply, and price.
As for the logistics sector, it grew virtually from one single company, Transport Corporation of India Limited, which is a closely held company of the Agrawal Family [now the company has been divided into GATI Ltd., TCI Ltd, Bhoruka, and other such firms]. They initially appointed people basically from their village, who were hardly 4th or 5th class pass. These people were able to join for a much lower salary than others [though the intention was to help their fellow villagers]. Some of the 4th or 5th class people performed well and were promoted to higher levels. Later, TCI started recruiting graduates and postgraduates. These employees needed to be paid higher, but at the same time, TCI had fixed pay grades, so the salary was not increased.
Almost all major Indian transportation companies have grown out of TCI, [either relatives of Mr. Agrawal or ex-employees of TCI], and they followed a similar pay structure.
Since the late 1990s, the salaries in these sectors have substantially increased with new players [such as Safe Express, TNT Worldwide] coming in to attract the available talent.
