$9k a month after tax is about $150k before tax.

The median individual salary in California is about $50-60k

$480k on its own (ignoring stock) is a ridiculous level, it's $285k after tax.

Yet someone with $1b in investments "earning" 10% makes $270k every day.

Someone with a "mere" $10m makes that $480k gross every 6 months.
