Some clarifications:
I didn’t say that meritocracy was the cause that “justifies inequality among human beings.” I think I needed to provide more context. Meritocracy is a rationale that seeks to allocate resources based on effort and merit. I have no problem with that. I was rather talking about meritocracy as an ideology used by some people in the real world here in Mexico, to justify why some have more than others. They attribute everything to individual effort and erase the true reasons why many people obtained certain resources: social status, class, inheritance, corruption, theft, plunder, violence, etc.
Of course, I value the testimonies of those who have succeeded in achieving actual freedom through their own merits, because it has nothing to do with anything other than their own merit and effort. In this case, the purpose suggested by meritocracy truly applies. That’s why, before writing that final statement, I was thanking @Kub933 for all his success and progress reports, which are very helpful to me.
My apologies, I wrote a problematic final sentence without being clear and without providing context. And I think there are aspects I need to analyze more closely, as to why I came to link one thing with another.
