But that's to collect statistics for the US Government.
If you as an employer were to take _any_ actions based on that information it would be illegal.
So after you get hired and provide that information for government statistics collection, why would your employer ever need to ask you for it afterwards?

Because your employer wants to collect statistics too.
They aren't "barred from any action", they can, e.g., publish reports on those statistics - it sounds like you don't even want the questions to be answerable...
Why? Who cares about this and what's the reason they must care?? Affirmative action? Race "quotas"?? How do you know it will not be used in the exact opposite manner? It's simply better to treat everyone equally (I know, radical notion) and stop this madness.
