Agree that American business culture is too short-sighted.<p>The question is size is far from decided, though. Though these Japanese firms may <i>survive</i> long-term, they often aren&#x27;t good stewards of shareholder capital as measured by return on equity (ROE) and other financial metrics. But it does seem that conglomerates are making a comeback, with Alphabet, Amazon, and the perennial favorite Berkshire, whose own CEO has said their size is starting to present problems. Definitely an interesting question.
