The bolded section is where I got the term "improved opportunity". With that statement, I agree. You then used the phrase equality of opportunity. The first bolded portion is not the same as the second bolded portion.
I would love to read your argument that equality of opportunity is not hindered by prior injustice. I work in wealth creation and preservation and I can tell you that a 350 year pause on wealth creation has exponential effects. Einstein said it best, "compounding interest is the most powerful force in the universe". Lack of wealth leads to lack of influence. Lack of influence leads to lack of education. Lack of education leads to lack of opportunity (or diminished opportunity).
Sure, under the law, the opportunity may technically be equal (like Plessy vs. Furgeson), but the issue is whether or not the opportunity is ACTUALLY equal. Reparations won't fix it. Affirmative action won't fix it. The great society didn't fix it. The sexual revolution didn't fix it. I'm not advocating for legislative action necessarily. I'm advocating for acknowledging the impact of the past and living in that reality as those who have better access and opportunity.
A thriving black community is good for America.
