Without the system, it is impossible for anyone to get rich. People get rich not through their efforts alone, by is reliant upon a multitude of factors that grants the person opportunity while also feeding upon the efforts of others who may have contributed to the infrastructure in significant ways but doesn't rip the same degree of benefits. One example is how CEOs gets to dictate how much they themselves are being paid, while essential hard workers at the bottom may be paid slavery wages and struggling to survive (depending on food aids funded by tax payers to allow them to survive).

"Universal income" on the blockchain imposes a fair and just automated taxation of those who have benefited from the system, and re-injects it back into the community. Putting resources on the least wealthy (who would spend those funds almost immediately on necessities rather than stashing the wealth aside) will continue to drive the economy and keep the whole economy healthy and going, which in turns benefits everyone, including the rich.

A free market system will ultimately be rigged by those with the most resources to their favor, and eventually the whole system isn't really a free market anymore.
A balance between a free market while satisfying people's basic socialistic NEED is a good idea, to maintain the society. Too many angry and frustrated underpaid and overworked struggling poor workers, and the underemployed and jobless, and society will eventually crumble as a whole.

However, to maintain a socialistic democracy is difficult as there are not many politicians that are proven to be consistent, reliable and sincere to the cause. However with blockchain based governance, democratic socialism can work.

Also it needs to be said that there is a BIG difference between a socialistic DICTATORSHIP (e.g. Venezuela) and a socialistic DEMOCRACY (e.g. many European countries, such as Switzerland). Socialism isn't the problem with Venezuela, but an incompetent government controlling the country as a DICTATORSHIP is.
