Anyone with a base salary of $300k can obtain a similar payoff structure by taking out a $550k loan to invest in GOOG, and taking out additional smaller loans at each stock refresh. The tax benefits from capital gains/losses and time-value-of-money benefits from getting your bonus sooner should handily outweigh the cost of servicing the loan, but even in a worst-case scenario where you pay interest for no benefit, that example Google offer would be a lot more comparable to a $315k-$330k salary, not a $1M+ salary.
On the other hand, this, my friend, is absolute nonsense:
> Anyone with a base salary of $300k can obtain a similar payoff structure by taking out a $550k loan to invest in GOOG, and taking out additional smaller loans at each stock refresh.
This is only equivalent if you ignore downside risk, which in the case of an average young professional with no significant assets could ruin you. The RSUs give you significant upside over 4 years with absolutely zero risk.
Also you said this:
> The fact that a particular investment decision (GOOG) can accidentally push the individual's yearly increase in net worth past $1M
This makes me think you might not understand how RSUs work. They are W-2 income at the valuation at the time of vest. What we're talking about is 7 figure annual income. Not investment gains over time.
