Ask HN: VC spread risk why not employees

Looking at how VCs spread their investments across many different startups, we should try to foster a model where employees can join multiple startups (with commiserate equity). Kind of like Freelancers Union where they pool for insurance coverage, and then work %time at a variety of startups which can offer relative salary. Would this make startups more attractive than FAANG b/c you hopefully have a better chance of some upside? Y would be a great place to help start this land build a marketplace for work.
