You'd have to specify what you mean by "Built the USA"
In terms of the founding/ideas that laid the framework for the USA, I don't think it's any secret a decent sized chunk of the founding fathers were White Male Protestants. (Though there were a percentage who were what was called "Deists")
In terms of the "building" as in "physically doing the labor", obviously there were other groups that did a lot of that.
It's idea/vision vs. execution dynamic.
For example:
Let's use the company Apple as an example...
Without the developers and "techy people" of the era grinding away, the ideas of Steve Jobs wouldn't have come to fruition
Flipside
Without Steve Jobs' ideas, those tech savants wouldn't have had any sort of clear vision of what to work on
"Equitable" (in terms of the modern themes of equity) -- sure
"Fair" -- it would probably depend on the aspect.
To provide an example
So if we look at the major accomplishment that was the perfecting of the modern assembly line for mass production...
Henry Ford and his team were all men
The workforce of 13,000 people (in total) had fewer than 50 women working there (typically in clerical roles)
So if someone tried to shoehorn in some reason why "Women were just as instrumental to Ford's success as men" to serve a narrative, that would tend to fit in with the modern definition of "equity". However, it wouldn't be accurate or fair.
However, if you juxtapose that against, say, NASAs major accomplishment of the Apollo Moon landing project...
The MIT instrumentation team that created the software for it was hugely vital to the project, and was led by a woman (Margaret Hamilton), and that team she led was comprised of 4 other women, and 3 men.
In that scenario, history putting all of the focus and glory only on the men that were involved with the Apollo project (the astronauts themselves, and which ever government department heads signed the checks) would be a legitimate unfairness that would be worthy of correction.
If we look at education:
Degree Type | Men | Women |
---|
High School Diploma/GED | 30.1% (as highest attainment) | 27.0% (as highest attainment) |
Bachelor’s Degree or Higher | 36.2% | 39.0% |
Master’s Degree | 10,156,000 | 13,725,000 |
Professional Degree (e.g., Law, Medicine) | 1,869,000 | 1,584,000 |
Doctoral Degree | 2,644,000 | 2,203,000 |
(women are beating men in that category)
If we look at the same data by religious affiliation:
Religious Group | Less than High School (%) | High School Diploma (%) | Some College (%) | Bachelor’s Degree or Higher (%) |
---|
Hindu | 2 | 10 | 11 | 77 |
Jewish | 3 | 16 | 22 | 59 |
Buddhist | 2 | 18 | 33 | 47 |
Muslim | 6 | 30 | 25 | 39 |
Catholic | 16 | 31 | 27 | 26 |
Protestant (all groups combined) | 10 | 36 | 33 | 21 |
Atheist | 4 | 22 | 31 | 43 |
Agnostic | 1 | 21 | 36 | 42 |
Nothing in particular | 10 | 34 | 32 | 24 |
All U.S. Adults | 16 | 31 | 32 | 27 |
(protestants are literally at the bottom in terms of Bachelor degree attainment)
Income by religious affiliation:
Religious Group | ≥ $50K | ≥ $100K |
---|
Jewish | 70% | 44% |
Hindu | 68% | 36% |
Episcopalian/Anglican | 68% | 35% |
Presbyterian (Mainline) | 66% | 31% |
Unitarian Universalist | 63% | 30% |
Buddhist | 61% | 27% |
Catholic | 57% | 26% |
Muslim | 52% | 19% |
Orthodox Christian | 51% | 20% |
Jehovah’s Witness | 50% | 20% |
Protestant (all groups combined) | 50% | 20% |
Protestants are bringing up the rear on that one
If we look at certain major cultural institutions (academia, entertainment), I don't think much of it (if any) is actively conveying a "pro Male Protestant bias" by any measurement -- in fact, "While" "Male" "Protestant" are probably 3 of the most criticized traits in in the past 10 years.
I would say if that if there's anything that's a "threat to While male protestants" (admittedly, I'm not a huge fan of the way that's worded), it's the overarching narratives that everyone who is all 3 of those things has a duty to self-flagellate and atone for the cultural sins of their grandparents and great-grandparents.
Two things would go a long way in that regard
1) Embrace the trades
2) Remove the college requirements for the litany of non-trades fields that don't actually have a practical need for it, and are just arbitrarily requiring a bachelor's degree, and replace with it much less expensive 12-18 month vocational training.
Netherlands has been moving toward this model, and Switzerland (one of the more affluent countries on the planet) has embraced this model for a while, with over 70% of their younger people opting this more slimmed down (and less expensive) targeted vocational training over the traditional university model.
Obviously certain fields (like medicine, law, and a few select others) have a legitimate need for a more advanced education and more schooling, but that's certainly not true of all fields currently requiring it in the US.
