Stable relationships are symbiotic not predatory
In thriving natural ecosystems, the denizens rely on a heavily give and take kind of connection and thus ensure the survival of the whole ecosystem. For instance, a bee will rely on a plant´s flower to get its nectar for food and the flower will rely on the bee for reproduction as it transfers pollen when it flies from flower to flower. Should the relationship turn predatory whereby the bee gives nothing back it would cause a reduction in the members of the flower´s species which could lead to possible death by starvation for the bees.
The same can be said for human connections like friendships, employer-employee relationships, romance etc. Friendships are built on a support system packaged with emotional support, life advice, company keeping and even sometimes for financial support while successful romance at its very core is a partnership program. Should they turn predatory it would cause an overreliance on one side leading to the eventual collapse of the entire system due to exhaustion of resources. It would also prove why the carrot and stick approach is particularly effective in superior-subordinate interactions such as between employers and employees. Another fine example would be bottlenecking in a pc. If either the GPU, RAM or CPU can’t provide data to the rest fast enough, the others will have to spend time idling, waiting to receive that data, which would result in low performance for the user turning the relationship predatory instead of symbiotic.
