Ciro Santilli is extremely passionate about this issue, partly due to Ciro Santilli's self perceived compassionate personality.
Ciro Santilli's main approaches to reduce it:
One of Ciro's most direct experiences with social inequality is described at: São Remo, the favela next to USP.
We have to be careful not to make everyone poorer when trying to reduce inequality.
But as things stand as of 2020, increasing taxes on the very richest, and notably wealth tax, and investing it in free gifted education, seems like a safe bet to achieve any meaningful level of equal opportunity and meritocracy.
Ciro Santilli is against all affirmative action, except for one: giving amazing free eduction to the poor.
Notably, Ciro is against university entry quotas.
Grew tremendously since the 1990's, likely linked to the Internet.
