In most industry sectors, merit, hard work and experience are valued.
A fresher can make mistakes, big mistakes which are very expensive and waste a lot of time.
Both the seller and buyer suffer losses due to the mistake of an inexperienced person.
Today the syllabus in colleges is very different from what the industry needs.

Training fresh employees according to customer needs is very time consuming and expensive.
Hence experienced persons are valued and respected, they can teach freshers, help them become productive soon.
However, this is not the case for other industry sectors.
