Throughout history almost in every culture except Israelites and even in modern times people tend to divide man on the nature of the job they do.
People have developed a mindset that those who do manual work are inferior.
Manual work is looked down.
For example in medieval Europe, man was divided into noble class, merchant class and labour class.
Some cultures gave religious color to casteism. They convinced people to believe that God created people to belong to certain caste.
Mosaic Judaism and Christianity taught a principle different from all these cultures.
In Bible God gave the job of tending plants in the garden of Eden. Post expulsion from the garden man’s primary job was to take care of the land. Man was not a hunter and gatherer of food as evolutionist believe. Man grew food and entire humanity were basically farmers and manual workers.
All men lived a self sustaining life. They grew their own food, they built their own house and made their own furniture.
Their primary education was to know God.
As some men of means got others to work for them, they developed a view that those who have people work under them is superior to the ones work for them. This mindset made men of means to do less manual work and depend on others to do manual work.
In the economy of ancient Israel all men were given an equal portion of land. All Israelites were farmers and manual workers. In the culture of Israel all men were required to learn manual work. In the school of prophets manual work was part of their education. There was no caste system in Israel.
Christ lived in a time when humanity looked down upon the labour class. But God the Father sent His son to be a carpenter. He knew manual work is important for His son to prepare for His ministry. Son of God came to serve not to be served.
To answer the title which caste does Christ belong to. In God’s eyes there is no caste.
All men are of one blood
And hath made of one blood all nations of men for to dwell on all the face of the earth Acts 17.26
God hates caste
Caste is hateful to God. He ignores everything of this character. DoA p403
Christ came to destroy caste
No distinction on account of nationality, race, or caste, is recognized by God. He is the Maker of all mankind. All men are of one family by creation, and all are one through redemption. Christ came to demolish every wall of partition, to throw open every compartment of the temple, that every soul may have free access to God. Col p386

The Saviour ignores both rank and caste, worldly honor and riches. It is character and devotedness of purpose that are of high value with Him. Cch 283
In the religion of Christ there is no caste
The life of Christ established a religion in which there is no caste, a religion by which Jew and Gentile, free and bond, are linked in a common brotherhood, equal before God. Cch 289
