The problem is though that this isn't down to some freak disaster or accident, there are very noticeable and obvious reasons as to why our generation may end up being worse off than our parents, and most reasonable attempts at pointing this out are often shouted down or dismissed. Similarly, youngsters today often face being called snowflakes or are perceived as being 'weak' by the very same generation whose greed has left us in a worse off position economically. I'd understand annoyance at the anger of many young people if older generations were realising their mistakes and rectifying them to help us - the problem is that they're doing the exact opposite, presuming you're not keen on Trump or Brexit. Youngsters who aren't well-off or who are struggling are often just told they're not doing enough to get a job when the reality is that a lot of jobs aren't available now, and we live in an economic system where you're inevitably going to get some people who fail and need the help of the state - the very same system plenty of people have/or want to dismantle in many first-world countries.
The idea that things are just a little bit worse off as well largely depends on how the next few decades go as well. At the moment it may only be a slight reduction in material status we face, but if the climate continues to worsen things could get dramatically worse. And I'd say there's not really any room to sit around and hope such an issue goes away: it's got to be addressed, and (again) it's mainly older generations who caused the climate crisis who are hindering progress on that regard, or who deny the issue altogether. Again, the anger here is very understandable.
I do get what you're saying. Some of the leftists on here don't particularly offer anything substantive other than snide remarks at times and don't particularly contribute to the discussion. Similarly they often seem so angry and dismissive of anyone who doesn't share their own views that you're often not sure as to who they're trying to help. By the same token though, they're coming from a perspective where 'niceness' hasn't particularly helped the left in recent years, and has often just been a code word for centrists implementing fairly right-wing policy. Similarly the rise of Trump has shown that plenty of people are ultimately willing to vote for a politician who's uninterested in compromise and is brazen in promoting his own agenda, something the left arguably believe they need to do as well. I get the need for civil discussion but at the same point civil discussion is only often possible where people have views that come from a reasonably similar spectrum, where disagreements are minor, instead of being cases where people's entire political philosophies are at odds with one another. So, yeah, I get what you're saying. But at the same time I understand why a lot of youngsters are ultimately sick and tired of being told to engage in respectful discussion.
