The reason behind your point is pretty simple too. Technology has never evolved to this much extent in the past and internet has never been used as much as it is at present. Millennial generation spends most hours of the day surfing internet. They are more comfortable with machines and computers as compare to their adults. This generation also wears the face of future bitcoiners.
The internet is around more than 20 years and not only millennial generation are experts in that, the older generation does outdoor activities too and not to glue in front of the computer all the time but the present generation is different and it will cause many health issues too, obesity in a major issue as they are not interested in outdoor activities nor working out and a healthy general is what we need rather than just nerds who can sit around the computer.
Yes that's why I don't disagree with the OP that millennials are screwed, as in fact most millennials now are career oriented, they prefer to become successful rather than wasting their life doing something they don't want, so for me this statement is not true at all, as it is not compatible to all people, maybe there were few persons who are lazy by nature and we can't do something about them.
If we will observe our environment, we will realize that it is not the truth. We can see a lot of millennial that are really spenders where they spend most of their salary from their job that they don't really enjoy to buy the things they want to impress the people around them that don't even give a damn about them. Millennial has a lot of opportunities around but they choose to screwed themselves up by forgetting about the importance of financial literacy.
