Meta's big job cuts aren't about the tricky economy or rising inflation. They're about Mark Zuckerberg's mistakes.

• Meta laid off 10,000 staff on Wednesday, adding to its November job cuts.
• CEO Mark Zuckerberg said it was economic changes that led to over 21,000 in total being laid off.
• Investors have long said that Zuckerberg's own decisions and mistakes led to this point.

Meta CEO Mark Zuckerberg sent a letter to staff announcing a second round of layoffs on Tuesday, just months after its last round of big job cuts.
