The only option I have is to shift into international markets and even that isn't too much of a shield as many of those have US allocations that will be buying SpaceX

So I thought I had that setup, but it so happens that I ended up with two 401ks at the exact same provider via two different companies, and there are different options between the employers.

I don't see a particular pattern as to why one would be different from the other, but they are...

Sorry, it's the same as you're describing. The employer doesn't decide which funds are available, the bank does. I'm thinking back to my last job and there were only about 10 funds to choose from, but I couldn't tell you who was responsible for limiting the options. The bank might have offered a "retirement benefits package" to the employer to simplify things. Not sure.

Because the employer can get the money back I guess!
