As multiculturalism becomes more prevalent, ironically, we will start to see a decline in culture. Different peoples are too distinct from one another to create any sort of meaningful identity, when their native cultures are combined.
This would lead to a society in which the only things we can find that we have in common with each other are our natural impulses and feelings. Culture forms when everybody has similar tastes and interests, but with people so different from one another, we will only find...
...similarities in our hedonistic and sinful desires, such as lust and mass consumption.
This trend, combined with the rule of corporate oligarchs, would lead to a society dominated by producers. The rise of product and the decline of culture is their agenda.
