I think your Dad’s probably right that if a company wanted a young person mainly for his functional accounting skills in the here and now, it would hire the pure accounting grad. But one’s career shouldn’t be measured with a snap shot of one place and time. For his entire career and life, a young person ideally should study something broader in order to employ skills and knowledge across the various functions of an organization. Your Dad himself, even though he says he regrets not specializing sooner, may prove my point by virtue of his success.
