"Never before in the history of western politics have we had the wealthiest coalesce around the leading political figure of the time."

Perhaps if by "western" you mean "USA." But if you acknowledge other than USA examples, look at pictures of Hitler's inauguration-equivalent ceremony. You will see a lineup of Germany's "captains of industry" of that era right there with him. From an economic ideology perspective, he was the uber-capitalist candidate that would protect them from the considerable anti-capitalist sentiment of that era.
