Sure, moving quickly and being able to see what others missed helps in starting up big time wealth generation: but to stay in the big leagues, government connections to back cartels, monopolies, and licensing restrictions “to protect the public” goes quite far.
And most Imperial dynasties and ruling houses are uninterested in the hard work to stay competitive in the free market, when they can use the cheap and easy ‘stroke of a pen’ to make laws to punish innovators who take ‘their’ profits and ‘their’ customers.
Fortunately, not even the Vilani-culture nobles have been able to recreate the truly static, unchanging economic structure of the First Imperium. When large tyrannical systems die, they stay dead. Even when partially rebuilt, the old times never truly return: the Second Imperium was a freer place than the First, and the Third freer yet.
And, in the 1248 Milieu, the Fourth Imperium is unlikely to ever truly reach the scope and scale of any of her predecessors. The only real possibility of doing so was if the Domain of Deneb/Regency of Deneb had remained united: with her huge economic advantages over the ruins of the rest of the Imperium, she could have successfully reasserted Imperial Authority over ex-Imperial Space… but the Regency fell apart.
Sadly, businessmen are generally libertarians when they are small… and fascists (“government-business alliance”) when they are big. There are those who are able to resist crying out for government protection when times are hard, but they are few and far between.
And who hears (…or cares…) about those few men of integrity? Who sees the legacy and benefits, resulting from the evil and the corruption they did not do?
No one but God, man. No one but God.
In our actual history, this corporate nonsense has been going on since at least Charles I (“Why Lovers of the State Hate Uber” https://www.garynorth.com/public/14332.cfm), if not far, far longer. In Traveller history, its a deeply Vilani thing, so you have shadow-emperors (who were also megacorporate leaders, of course).
And in Marc Miller’s Traveller (a.k.a. “T4”), Emperor/Business Magnate Cleon Zhunastu built his fortune from a variant of cold fusion, Fusion Plus.
