Diversity Tech and the Multiracialism doctrine have totally destroyed the strategic competency of western countries. It is the biggest unforced strategic error of our modern times. If I had to plot out the consequences, like in a sid meier strategy game, I would summarize it as something like:
DIVERSITY PROGRAMME
-1 to morale
+1 to discord
-1 to science
costs 1
MULTIRACIALISM DOCTRINE
-2 to morale
+2 to discord
-2 to science
costs 4
So as you can see, they are exactly the same and their effects stack. What's worse, multiracialism cannot stabilize without diversity, and as a result the two go hand-in-hand. This then results in a morale crisis, a discord crisis, and low science production figures, and high public expenditures. So you get a country with high discord, without will to fight, which cannot produce competitive GDP output, and which is highly expensive in welfare upkeep costs and likewise.
This then requires the political system switch to dictatorship, because the discord rating is too high creating anarchy. And economic socialism, because the costs are so high. Which then zeros in on a low productivity, low innovation, and low strategic competency nation. And results in you losing down the line because no intelligent competitor would ever do this.
