Jesus was not a socialist. He was a REALIST. Jesus’s values and philosophy never even approach that of socialism. In fact, if anything, Jesus was a capitalist. Jesus was a carpenter by profession and trade and it is that how he made his living. It is only later in life where he became a preacher and teacher of Christianity. But Jesus lived by the precepts of Christianity long before he began preaching about them. Of course back then there was also a barter type system, an exchange of trades and services rather than currency.
John 1: In the beginning was the Word, and the Word was with God, and the Word was God. 2He was with God in the beginning. 3Through him all things were made; without him nothing was made that has been made...
14The Word became flesh and made his dwelling among us.
So Christ is the Word of God. So EVERYTHING in the Bible is from Christ, NOT JUST the words he spoke while a man on earth.
The words telling of the rewards for searching for and living by wisdom.
The consequences of foolishness.
The reward of hard work and dilligence. The result of laziness and sloth.
That a good parent LEAVES an inheritance to his children.
That a bad parent doesn't provide for his own.
A wise man builds his house upon a rock, so WHEN the storms come, it will withstand.
A fool builds his house on sand, and WHEN storms come it is destroyed.
The word also tells us of a woman who gets up early, to prepare for her children, husband AND servants.
It tells us leave some grain in our fields for the poor.
It tells us the story of the good Samaritan.
It tells us that GOD IS THE SOURCE of all blessings.
The Word tells us that those who bless others, will themselves be blessed.
We are commanded to help the poor and sick and orphans and widows.
But never does it tell us that we should all have all things equally.
Like you said, Jesus was a realist. The reality is that Jesus was the one who implemented what we call capitalism. But his "capitalism" is one of responsibility and blessing.
One I'm thinking of off hand is the one where the master who called his three servants and gave one 10 talents another 5,and the last 3 talents to take of care while he was away.
