Technology is of most benefit to those who are most enslaved. It is common to find the poorer the country, the more basic the system of enslavement is. In the US, it is a highly sophisticated system, such that most people arent even aware they are enslaved.

That said, the benefit is that a technology like blockchain and crypto enables the surpassing of the enslaving controls no matter how strong. One of the biggest problems with financial aid from first world nations to Africa is that the money is often robbed before it gets there. This is something that is eliminated with crypto.
