Maybe he had two Ferraris because he was frugal with his business?
Why does everybody think it is absolute must to maximise the profits? Maybe he was ok with his profits and just didn't care to optimise his business as long as he has comfortable life? Is there something wrong with it.
Over the years I have worked as an advisor with many owners and CEOs of various sized companies (up to couple thousand employees). I had many situations when those CEOs would confide in me how disappointed they were in some of the decisions their employees made when it comes to finances. Especially high level leaders, who should know better. As a rather typical example, situation when an ex-Microsoft director hired as new IT director would sign a contract with Snowflake to commit 300k USD over 3 years for a 10% discount. The issue is I calculated if we did not commit, we would actually pay about 500 USD/year. Yes, not 500 thousand, just 500 USD. After that we have instituted a near total ban on commitments as a recognition of the fact that we just can't predict the future.
Or people that would start some expensive stuff on AWS and then would just "forget" to turn them off. Or a guy who thought it is ok to pay almost $100k for a marketing stunt where they would livestream with a single webcam a bunch of grazing cows for a week.
Yeah, it is kind of easy to waste money when it is not your money.
