Presume that everyone making above, say, $1 million per year isn't taking all their income as W2 income. How much this counts as "hiding" income is up to you to decide, but generally W2 is considered "normal people" income, 1099 "contractor people" income (whether that's a plumber who owns their own business, or an Uber driver), and 1099-DIV and 1099-INT and related are rich people incomes.

If we further assume big tech companies have 5 CxO (CEO, CFO, CTO, COO, CISO, CMO; pick 5), and that there are more than 1 big tech companies headquartered in California. If we assume those officers make large incomes that aren't W2 incomes, that they live in California, and, further, live in areas serviced by PG&E (which, statistically speaking is basically all of them), and then count individuals based on the fraction of income "hidden" as non-W2 income, and sum them up, then that number is surely greater than 5.

Not a statically significant portion of the 17M employed Californians mind you, but more than 5.
