That is absolutely true. That's what Critical Race Theory is all about.
You are wrong about diversity.
Europe was the last and slowest to develop technology, not the first, with the industrial revolution.
When Mediterranean cultures were making complicated machines, aqueducts, stone arches, plumbing, etc., Europe was living a stone age life in mud wattle huts.
The first industrial revolution was around 2000 BC, and invented blast furnaces that could make steel.
The Romans essentially were the pinnacle of industrialization, around 200 AD.
They invaded Europe and taught the Europeans how to industrialize.
The European industrial revolution around 1800 was not very significant in comparison.
All it did was create steam power, and switch from burning wood to coal.
The result was not even very good, since mostly what it did was force cottage industries to go bankrupt, and for everyone into semi-slavery in factories.
Industrial advances in technology do not come from any racial difference, but in cultural ones that you discover best with diversity.
When you have prosperity, that allows the best and brightest to have enough free time to explore their greatest potential and ideas.
That does not require any particular racial traits.
The oldest analog computer is the Antikythera, from around the year 0.
That is way ahead of the industrial revolution of 1800.
The advantage of diversity is that all cultures are simply habit, and because of that, all cultures do somethings wrong.
But without other cultures to look at, you don't know what you are doing wrong.
Like slavery.
It harms the whole society by putting profits above empathy, which eventually destroys any society contaminated by it.
But when money rules, no one realizes the harm the loss of human rights causes.
