For most working persons globally, getting fired isn't something that involves a "difficult conversation". Working stiffs do not get that degree of attention to their feelings. Suggesting that this phenomenon is common to (or even characteristic of) the high-income and acutely socially-aware circles of Silicon Valley should not be construed to exclude its observation elsewhere, but SV is one of the few places where the behavior is common, and hopefully the only place that feels the need for a polite euphemism.
