They are arguing the reverse, high wealth folks in SFHs are higher emitters.

You'll be fine. While DC enjoys drinking there are tons of sober events and options for folks who aren't about that life. I don't really enjoy heavy drinking (a glass of wine with dinner max) and I've honestly never felt left out or limited.

Ah, interesting. TIL it wasn't always an independent agency, I'm young enough that all my interactions were with it as an independent one (I didn't deal with them much as an elementary schooler lol).

IRS doesn't deal with SSNs, that's the social security administration (SSA).

That said, that's rough for your mom. My issue with mine wound up being amusing and simple to fix rather than an enormous pain. Apparently when mine was issued it was marked as female (I'm male and was born as such) which triggered some fraud alerts when I started my first job. For me the fix was a simple trip to my local SSA office and saying "I'm male" but I've heard plenty of frustrating stories trying to sort out different issues.

Thankfully SSA has realized that system was a significant security risk and has moved to a randomized system (although most people will still have the old setup).

Good luck, when we found a mouse my cats just stared at it kinda confused before getting bored of it.
