Interesting that YC is jumping on this tax code thing, but the shitty tax situation for employees trying to hold onto the equity they've earned is just ignored.
The number one problem for startup employees is that the AMT tax makes it impossible to exercise options in a company that is doing well. YC is showing us that they will fight for changes to the tax code when it benefits their bottom line directly, but are silent when it comes to helping startup employees hold onto equity that they have earned.
Think carefully before joining a YC startup as an employee.
