Quote from MrDODGE:
You would be amazed by how many students want to be I-bankers when they know nothing about the job or hours required. They want the prestige without doing the work.
They want the money. Of every 100 that makes it on to the Street, only 1 will ever become a banker. The rest either remain clerks or else are forced to seek alternative employment as many are now discovering they must.
