Yup. Those numbers aren't surprising.
If you're a decent software engineer and live in San Francisco, Boston or NYC and you buy a house today, by the time you retire, it will probably be worth 1-2 million.
Then other stuff in the summary:
being most valued employee at your organization. If you exclude the execs, yes, software engineers probably get the best work to salary + benefit ratio if any profession right now.
Any decent software engineer who doesn't get a raise this year is probably quitting faster than their employer can tell them the news, and will start their new job with an extra 10-20% pay tacked on before they finish their sentence.
In place worth working at, outsourcing is frequently used for level 1 and 2 support, click testing (so actual QA Engineers can do something more meaningful), and to deal with legacy software no one else wants to touch.
Its not that way everywhere, and that's why the numbers aren't 100% in every category. But they seem about right.
