One thing I have noticed is how prevalent the hustle culture has become among Millennials. LinkedIn is a hotbed of narcissism, and Twitter has a ton of self-proclaimed business superstars who have made money by having companies entirely dependent on using foreign labor and providing shitty service for customers. It's quite appalling how often you hear fellow Millennials go on and on boasting about their own "successes" or try to sell themselves without an ounce of honesty.
The hustle of creating "passive income" means that we are going to see a lot of sociopaths becoming landlords and doing the bare-minimum for those who rent from them, and the quality of services will continue to decline across all companies as there is no value in providing a good service, merely making money. The decline of quality we have seen from the boomer generation onward (yes, that includes you, Generation X, you aren't exempt from being self-destructive narcissists like your parents and your children) is going to ramp up significantly.
Some people will say, "blame the system, not the person," but for god's sake, eventually someone has to stand up and refuse to operate as basically a scam artist. For as many supposed "leftists" there are among Millennials, they sure have no qualms about taking the worst aspects of human greed and using that as their core business model.
Am I over-exaggerating here?
I don't see the problem you've described at all.
My understanding of the problem you've described is that you feel millennials are doing anything they can to make money which includes being a slum-lord and therefore quality of service is going down because millennials care more about making a quick-buck than they do about quality-of-service. Correct?
Again, I don't see it. I see slum-lords but not millennials. I don't foresee there being any significantly more slum-lords in the millennial generation because of their pursuit of a quick-buck.
I also don't see anywhere in the market where quality of service has come down because of these things... You describe guys who do shitty work by outsourcing the work to other countries. Bro, is this the 1970s? That ship already sailed.
When I go through the drive-through and I get shitty service, guess who's working behind the counter? Shaniqua. It has nothing to do with millennial side hustles. When I call up tech support and get Rajesh on the line, I already know it's going to be a struggle and it's not because Rajesh has a side hustle. When I'm contacted by Hussein for some financial product, I know to be weary and it's not because Hussein is doing a side-hustle.
Check out the HR Departments of most major corporations. I can tell you why the quality of service is going down only from looking at the photos of the people in the HR Department. And it has absolutely nothing to do with millennials having a side hustle.
