Its true it seems that millennials is less educated and probably the worst generation where even in social media their post are annoying they're main concern in life is sex, drugs and alcohol. They spend more time in online games, burning their money doing meth & alcohol and social media than spending more time in productive skill development or investing their futures into something like crypto.
You just saw someone that doesn't represent the whole generation, yes there are some millennials that even their capability are just doing something stupid like that but there are some that really contributes to the society as the silly and foolish one usually stands out the most. You just don't need to be so pessimistic about this generation, if you don't believe just see the amount of startups that are growing everyday that definitely shows this generation is doing something and not just wasting their time as you said.
Right, there's a lot to look forward to with the current generation, and with the means that are available to them, they could go a long way. Of course there are bad eggs in every era, even for those born in the 80s and 90s. Though we had to exert more efforts then because we don't have the tools the this generations have in their disposal. Everything needs to be done almost manually. With the internet and technology progressing this much, you can say that this generation can afford to be more relaxed than us.
