Can't vouch for that poster, but his central point is solid: A lot of people here are squandering the opportunity they've been given. Even worse, many are actively sabotaging themselves.
His address t o the Thousand who governed the city, on the best ways of speaking and habits of life
The young men told their fathers what Pythagoras had said, and the Thousand summoned him to the council. First they thanked him for what he had said to their sons, then they asked him, if he had good advice for the people of Kroton, to give it to those in charge of government. He advised them first to found a temple of the Muses, to preserve their existing concord. These goddesses, he said, all had the same name, went together in the tradition, and were best pleased by honours to all in common. The chorus of the Muses was always one and the same, and they had charge of unison, harmony and rhythm, all that goes to make up concord. He explained that their power extends not only to the most splendid objects of thought, but also to the concert and harmony of being. Next he said that they must think of their country as a deposit made with them all by the mass of citizens, and must manage it so that they could hand on to their descendants what was entrusted. And that would certainly be so, if they treated all the citizens fairly, and attended above all to what is just. People know that justice is needed everywhere, so they made the myth that Themis ranks with Zeus as Dike does with Pluto and as law does in cities, in order to make it clear that a man who does not deal justly with his charge thereby commits a crime against all the universe. He said that councillors should not swear by any of the gods: they should deal in words which would be trustworthy without oaths. They should so manage their own households that their political principles could be referred to the standard of their private conduct. They should be generously disposed towards their children, for among other animals only people can grasp that idea, and each should behave to the woman who shares his life in the awareness that his contracts with others are set down in documents and inscriptions, but his contract with his wife is recorded in their children. They should try to be loved by their descendants not by nature, for which they were not responsible, but by choice, for that is a benefit voluntarily given. They should also be resolved that they would know only their wives, and that their wives should not adulterate the line because their partners neglect and injure them. A man should think that his wife was brought to him in the sight of the gods, like a suppliant, taken with libations from the hearth. He should set an example of discipline and self-control both to the household of which he is head and to those in the city; he should ensure that no-one does the slightest injury to anyone, so that instead of committing surreptitious crimes in fear of the legal penalty, they strive for justice out of respect for his nobility of character. As for action, he urged them to reject inactivity: good, he said, was nothing other than the right moment for any action. The greatest crime is to alienate parents and children. The best man is the one who can himself foresee what is beneficial, the second best he who realises, from the experience of others, what is profitable, and the worst he who waits until he learns from suffering to see what is best. People who seek honour will not go wrong if they copy those who win races: their aim is not to injure their opponents, but to achieve victory. People engaged in politics should help their supporters, not obstruct their opponents. Anyone who wants a truly good reputation, he said, should be as he would like to appear to others. Good advice is less holy than praise, for advice is needed only for people, but praise is required for the gods. He concluded by saying that, according to tradition, their city was founded by Herakles when he drove the cattle through Italy. He was injured by Lakinios, and unwittingly killed Kroton, who had come at night to help him, thinking he was one of the enemy. Herakles then promised to found a city named Kroton at his tomb, if he himself achieved immortality. So they were bound to administer it justly, in gratitude for the kindness Herakles had returned. Having heard him, they founded the temple of the Muses, and sent away the concubines it had been their custom to keep. And they asked him to speak separately to the children in the Pythaion, and the women in the temple of Hera.

Questionable if that individual understand the concept, but:
https://www.britannica.com/topic/social-contract
social contract, in political philosophy, an actual or hypothetical compact, or agreement, between the ruled or between the ruled and their rulers, defining the rights and duties of each. In primeval times, according to the theory, individuals were born into an anarchic state of nature, which was happy or unhappy according to the particular version of the theory. They then, by exercising natural reason, formed a society (and a government) by means of a social contract.
Although similar ideas can be traced to the Greek Sophists, social-contract theories had their greatest currency in the 17th and 18th centuries and are associated with the English philosophers Thomas Hobbes and John Locke and the French philosopher Jean-Jacques Rousseau. What distinguished these theories of political obligation from other doctrines of the period was their attempt to justify and delimit political authority on the grounds of individual self-interest and rational consent. By comparing the advantages of organized government with the disadvantages of the state of nature, they showed why and under what conditions government is useful and ought therefore to be accepted by all reasonable people as a voluntary obligation. These conclusions were then reduced to the form of a social contract, from which it was supposed that all the essential rights and duties of citizens could be logically deduced.

People misleading them,
Others deceiving them,
Obscuring the world in them,
We all are to blame.
