Answer:
Negative term for a business magnate implying that the Tycoon used unethical means to acquire Fortune is "Robber Barron".
Explanation:
"Robber baron" is a stereotypical term of social criticism typically attributed to certain American entrepreneurs of the late 19th century who have been convicted of using unethical tactics to enrich or increase their fortunes.
The concept was focused on a comparison with the German robber barons, regional feudal lords or robbers in Germany who were owed some tax or fine to the waylaid travelers across their putative land. As early as 9th February 1859 the metaphor appeared. The word blends the derogatory senses of thief ("robber") and aristocrat ("barons" in a republic that have no useful role).
