The more my curiosity has gotten me re-reading into this the more baffled I am that seemingly otherwise rational people have gobbled up S.A. Date's inheritance claim hook, line, and sinker. IIRC, even Date eventually admitted it was utter ********.
We don't know for a fact what the Donald inherited or when, but it's almost a certainty it wasn't $40 million in 1974, because a) his father's company wasn't liquidated until after his death 25 years later, and b) Trump inherited $177.3 million 2004. It is utterly irrational and illogical to believe his father who died a billionaire actually gave every red cent away in 1974.
2. Even if Trump was given $40mm in 1974 - this ludricuous number comes from Fred Trump Sr.'s net worth / 5 children - Trump increased his personal net worth to 5x that amount in 1982. An astonishing feat by any measure.
1982 was cherry picked because it followed a down year.
3. S.A. Date's claim accounts for as little as possible, to create maximum deception. No taxes, brokerage fees (once magnitudes higher than today), or Trump's lavish lifestyle, expensive divorces, loan payments, etc. were factored in. Purposefully. Trump easily spends ten figures annually to support his lifestyle. Keeping multiple mansions isn't cheap. The one he sold to the Russian was something like $75mm alone.
Take $15mm-30mm/yr out of even a billion dollar trust fund and your ending "performance" is going to drastically underperform a hypothetical. That Trump has even kept close to that benchmark while sucking so much cash out of his business ventures tells us his R.O.I. has quite likely been very impressive.
I guess I shouldn't be shocked that people don't see through ******** articles like S.A. Date's, and question them or poke the obvious holes. Passing this one on makes you the guy in the old joke about a person who believes everything they read in a chain email.
