Because many millennials want to have their cake and eat it too. You can't have it both ways:
- You can't choose to attend an $80,000 per year private liberal arts school and then complain you have too much student debt
- You can't move to the most expensive place in the country with no money and a low paying job and then complain it's too expensive
- You can't regularly use convenient and artificially cheap gig-economy services (like Uber and Instacart) and then complain when their business model doesn't support giving you a $150,000 a year job
- You can't demand free speech protection and then violently oppress viewpoints you disagree with (for the record, I am a political moderate)
The Millennial hypocrisy is astounding, but I'm sure every generation goes through this to some extent. The real generational moment of revelation is when you realize that every choice you make has consequences - and not just the choices/consequences you choose to believe. If I buy a cheap toy at Walmart, I know that some labor exploitation was involved. If I buy fruit at Costco, I know that burning of fossil fuels is involved. If I choose to use Google services, my data will be exploited for profit.
What everyone is asking Millennials to do is take some responsibility, acknowledge that your actions are part of the problem, and that you have some power to drive solutions. It's fine to lament about some level of inequity handed down from previous generations, we have all done it. What everyone is getting a little tired of is the classic Millennial argument that paints an entire generation as helpless victims and essentially says "You did this to us and now we want you to make the bad man go away!" Kind of like an entire generation of Robin Arryns for all you Game of Thrones fans.
