Okay, here's the post lol.
Creating buildings that give

(and thus promoting building wealth) have the following traits:
- need very early and very cheap technologies (Writing, Meditation)
- generate culture
- the total science multipliers after Scientific Method are 75% until superconductors
- culture buildings never survive city capture
- it's most certainly possible to have cities with +105%

and an Oxford with +205%

till Scientific Method.
It's not unheard of to have as much as +45%

multipliers in early cities with 2 religions with the benefit of also generating 6

Thus, the logical choice in the early eras is to push the science slider up and to build wealth.
In comparison, the MGB has the following traits:
- requier two moderately expensive and one relatively cheap technology
- the total multipliers are 100% already after banking
- can survive city capture
- are buildings that require a lot of

to build
-
does not open their superbuilding (Wall Street) with Banking
- more often than not, the Grocer and Marketplace
require trade with nations in different climate zones and/or continents to gain the full benefit of

investment.
Astronomy opens up many new trades, cities are already able to produce more expensive buildings (workshops with caste and guilds), thus realistically enabling a solid expansion of MGBs.
In my opinion (myriad exceptions put aside):
- build science from Alphabet to Currency
- build wealth from Currency to Scientific Method
- build tech buildings from Meditation to Education
- build wealth buildings from Guilds to Astronomy
