Why do families of the poor often have conflicts? It's because the lower class acts as a pressure release valve for society, a sewage outlet that absorbs all the dirt and excretion pressures of the entire community. When the sewer is clogged, who deals with it? The poor. When the trash bins are full, who handles it? The poor. Who takes on the dirty and foul jobs? The poor. Who does the exhausting and dangerous work? The poor. Any terrible task is done by the poor; any painful cost is paid by the poor. As society continuously outputs pressure, discharges dirt, and excretes waste, the sewer naturally gets clogged. Are there any exceptions? For example, some poor families are impoverished but still harmonious, with successful children and deep bonds. Such examples are rare, but they do exist. Their characteristic is that, although they are poor, they actively stay away from the sewer environment and do not accept society’s waste discharge and excretion. Society is a large machine that constantly extracts nutrients from the lower levels to support the upper levels, while also dumping the dirt and waste of the upper levels onto the lower levels. The typical disharmony in poor families is precisely because they maintain this garbage mountain, depend on it, rummage through trash heaps for food and supplies, and accept the sewage discharged from above. Atypical poor individuals are those who stay away from the trash heaps, eking out a living in resource-scarce wilderness. Both are poor, but their experiences are vastly different. The former’s poverty involves both physical and mental suffering—an endless hell of unfulfilled desires and mutual harm, impossible to resist. The latter’s poverty is physical hardship and spiritual emptiness, which can be somewhat alleviated on its own. Although the garbage mountain is dirty and smelly, it contains a large amount of discarded, unwanted resources from above. Recycling and utilizing the upper-level waste has allowed some poor people to become trash kings, achieving social mobility. They become middle-class trash collectors, even reaching the ceiling of the trash king’s status. But this kind of social leap isn’t without cost; to be one of the lucky few, trash collectors bear too much of society’s waste and pollution, which they cannot fully digest. They transfer some of this burden to their families, sharing it together. When family members can’t bear it anymore, conflicts and disputes increase. Even if some trash collectors win the lottery, the damage caused by their past experiences cannot be repaired. Wealthy people, middle class, families with conflicts, children turning against parents—these are all common. Everyone knows that money is good, social mobility is good, and striving for progress often means resorting to any means necessary, risking everything. But what is the cost? Becoming a sewage outlet to get promoted is a gamble with a price. This cost isn’t just for the individual but also for their family, children, and descendants. If they truly hit the jackpot, there might be a chance to heal the entire family’s wounds later. But most families of the sewage outlet are doomed to discord and generational hatred.
