Here's a visualization of her layoffs at HP
To be fair, I wouldn't mind some massive government layoffs.
A few hundred thousand NSA contractors doing surveillance, about 50,000 TSA agents who make people not want to fly, and some serious tax reform could eliminate the need for a few hundred thousand IRS workers. (The Lee-Rubio tax reform plan is much less terrible than the current tax mess, removing most of the deductions, credits, exemptions, and exclusions abused by businesses and individuals, and includes dumping lots of IRS workers.)
Couple it up with some H1B reform dropping anywhere from a quarter to a half of the 140,000 of the H1B visa jobs.
Round it out by firing a bunch of high-level and mid-level people in the agencies suffering from regulatory capture, but those can be filled with new people with an emphasis on avoiding capture.
So a half million or so workers. The layoffs will sting for a few months, but they'll make the country better.
For those, I'd mirror her comments "I would have done them all faster."
