From each according to his ability, to each according to his need.Karl Marx lived in a poor world. But the world has become very wealthy.
"We live in a world of abundance and wealth."If Marx had lived in today's world, his slogan might be this:
(From Unconditional Basic Income: 1,000 Euros a month for everyone!)
From each according to his ability, to each according to his share of the country.Since every citizen has one equal share of the country, this can be more specific:
Tax progressively according to income level, and distribute citizen dividend equally.A citizen dividend in a world of abundance and wealth is way higher than a "livable wage", and is way more than a person's need.
Here are a few examples of the "abundance and wealth" in this world:
Falkland Islands: US$500,000 citizen dividend for each resident annually.
Kuwait: $2.3 million citizen dividend each, over a lifetime of 80 years.
Equatorial Guinea: US$6,000 citizen dividend each.
Norway: At least US$5,000 citizen dividend each, and going up each year.
Singapore: $800,000 citizen dividend for each citizen, over a lifetime of 80 years.
