If you're thinking Space Race, then maybe we want IW. For diplo, no.
Wall Street is also not very useful since we are 100% research.
If we time it properly, there is no extra anarchy for HR. We just share the 1 turn for Bureaucracy.
Yes, you're right diplo is a beeline to MM, and probably we'll skip steel. But if it comes, IW is a good boost to production if we do not have health issues and if we can have it by trade or PA.
Wall street is pretty useless, if we're not running merchants.
But revolt in the same turn for Bureau means we need to MM the size 4 for over 30 turns, while loosing production and research.
I opened the save to take a look, and i'm a bit depressed: we lost the furs

(i should have miss the row, edit: now i see it, is at the beginning of Sweeta's Autolog).
Fred's power is prolly due to his knowledge of IW, but do he has Iron? or copper? JC surely has something, there's a mine in flatland near Rome.
What do you think about Music, for the great artist? it can be a sure shot if we manage to trade Alpha not before 3 turns
I propose this paths for research: (why not research Drama next turn, then switch to Poly until we can trade for it)
1) Lit - Music - Drama - and the shortest path to Bureau
2) Lit - Drama (if you miss it, i'd like to have the Globe, and i think that have no problems of happiness will help our research) then to Bureau
3) Lit - straight to Bureau
We got that damn Happy cap, and without fur and a religion we'll be at size 4 for millennia: no hope to take back the damn furs without a massive culture (64% american that tile

)
Another way:
Not research Poly at all, try to trade IW for it, and keep the research on Drama until we can directly switch to Lit. It can be done in 14 turns.
More: we need to continuosly MM the city to stay at size 4, and i can't see a way to keep the 2 scientists and build the GLib at size 4.
To do this we must be at size 5 or 6.
Do we revolt to slavery when it comes on line? not much useful, IMHO with that happy cap.
There's JC with a double gold city, we can try to trade with him, once we have a trade route and if we do not arrive too late.
