The general problem in the relation between young people and the government is that for various reasons most governments tend to give priority to other population groups. Older people are more reliable voters in a democracy. Richer people are better at lobbying or gaining political influence through donations. Revolutions on the other hand are nearly always fueled by the anger of younger and poorer parts of the population. Reminding governments of that is actually a clever move by these younger and poorer people.

Many people in government are not only old and rich themselves, they are also isolated from the real world and have a hard time understanding the current desperation of younger people. Rising inequality results in aggregate numbers like GDP being increasingly misleading. A trillion dollars more for Elon Musk or a trillion dollars evenly distributed among all US citizens would be the same in terms of GDP, but have vastly different outcomes in the real economy. Sometimes the young and the poor need to remind governments that things are not going well for them. In Europe these reminders often come in the form of more people voting for parties on the extreme left or right; America is rather handicapped by their two-party system, that doesn't allow that sort of expression. While the US government will get a rough reminder in the midterms, the Democrats will get a very wrong impression that they are doing the right thing, when in fact they are equally at fault for the current bad economic conditions (which was why Trump got elected for a second term). 

Young people having a generally negative outlook towards their own future is causing a lot of harm. Birth rates decline, some people simply opt out of participating in the economy, and in poorer countries a lack of hope leads to people emigrating. Some of the natural excesses of capitalism, like the increasing cost of education, and the decreasing quality of employment, are unlikely to improve without government intervention. A young person who did everything "right" and got a college degree, only to be stuck with large student debt, and the only jobs available being financially insecure in the gig economy, has good reasons to be desperate. While I don't support political violence, I do think that young people, lacking the political clout of older and richer people, do need to be somewhat louder and more visible in their protests.
