The easiest way to follow this advice is to take it to its logical conclusion and just offer your services on a contracting basis, as a single member LLC or a small partnership. At this point in the US tech industry the relationship between employers and FTEs is so tenuous that there isn’t much difference between the two legal arrangements in terms stability. I’ve kept my best clients much, much longer than my longest tenured FTE jobs.
And there are lots of benefits to being independent legally. Tax benefits aside, the pay is usually much higher, and you can/should take on multiple clients simultaneously. This leaves you less exposed to the whims of a single C-suite, and lets you stack up silly amounts of money when times are good.
Well, this is one of the reasons you charge more as a freelancer. It's ~$2k/mo for a family; even if I charged exactly the same as my market rate as an FTE, that would be less than the tax benefit I get from operating through a properly set up LLC taxed as an S-corporation. LTD and E&O insurance are other big expenses, but they're not prohibitive given the delta in hourly rate between FTE and C2C.
