What is the summary of the movie Parasite (2019)?

The struggling Kim family sees an opportunity when the son starts working for the wealthy Park family. Soon, all of them find a way to work within the same household and start living a parasitic life.

Greed is the main motif in Parasite and we have the chance to observe how toxic it is. The family who is living in poverty, motivated by greed, take an opportunity to exploit the wealth and naiveté of the rich. Kims believe that bad things happen only to them and that “it is easier to be nice when you are rich”.

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )
