There is not a lot worth buying that is long-lasting. Agreed. The economy went from making perennial goods to making consumable-like goods with planned obsolescence. Although it's more convenient to have subscriber-like clients than it is to have one-time buyers, in the end it's worse than having close to no clients at all. Cars and houses can be made long-lasting.
There is no reason to trust the banks. Yet, a lot of millennials fell for housing bubble and I bet they'll fall for other ones just as likely. In this regard there isn't some kind of inherited wisdom developed in our generation, unfortunately.
Credit rating is bogeyman. That's just American specific phenomenon, regardless how much resemblance carries globally the traits of millennial generation.
Cars are expensive and limited in utility. Cars always have been appreciated more in U.S., otherwise the utilitarian attitude toward cars was also shared by older generations outside America.
Our parents set our city planning up for failure. Yeah, the planning that would "actively discourage walking" is a trait that I've usually noticed in low demographic density areas, like Australia or Iceland. Other than touristic walking tracks, there aren't actually pedestrian access to get around much outside the city centers. That's therefore not so much because our parents' planning as it is a reflection of local population's habits.
Our government doesn't care about us. I am not sure if this is a trait not shared by previous generations in their prime. I hear that times were perceived rough in their days too, although it may be for different reasons. Older generations blame the government for not catering their needs enough as well.
Our government not only doesn't care about us, it schemes to make things worse. That's how a corrupted system feels like, and it doesn't take to be in a given generation for that.
Our companies don't care about us. I would say "yes, this may be something new", but I suspect that in the '30s, in America's Great Depression with the economy achieving overproduction and unemployment hitting high rates, the people felt the same. But, if we're about to compare our generation with only the last two before, then it may be true - nowadays it's worse.
We don't believe in advertising. That's tough. I don't think there ever existed an attitude for some commercial product like I've seen to be for Apple products, at least back a few years ago. Apple products may have brought some innovation, but so did other products that didn't enjoyed that much hype around them. What set apart Apple products was their commercial promotion. That, was like no other! And it caught, it caught big!
We don't believe in the police. You only notice that if you are in some disadvantaged social category, and it have been like this since the societies themselves. The novelty in this is that in America of our time the disadvantaged social category is becoming dominant.
We don't believe in the news. It's not so much as the older generations were more gullible as it is that the traditional news channels were often the only news they had. Access to some alternative media channels or the peer-to-peer sharing of information (news included) was very limited, unlike today. It's not a generation trait, it is being empowered by technological advancement.
We believe in each other. I am not sure about that. It's true that "the sheer amount of fakeness" made us more reticent to the known actors like traditional media, traditional advertising, and to traditional political play, but the stakes are high and the public belief is a high-sought currency. Influential bloggers, the ones that have an influence to trade are courted by whoever is interested, we all know that! Need to say more?
