This strain of leftism is essentially just jealousy and entitlement. I learned life isn't fair as a child it really isn't that hard of concept to grasp. That gave me the motivation to think about what I wanted out of life and to work towards that goal. I didn't get a loan from parents (they barely made ends meet growing up). I didn't go to college or a code camp. I worked delivering papers, then as a janitor ($5.65/hr), then a courier at a hospital before I got my first coding job. Instead of going out with friend in high school I stayed home and taught myself how to code. Now I have everything I want in life. I am happy. It just took actual grit and work.
There is, quite literally, endless opportunity in this country if you have the grit to find your own slice. But, because it is not dropped in some people's laps they cry foul.
Our modern society, which was created through capitalism and the defeat of socialism and communism, has lifted billions out of poverty, has made previously deadly diseases a thing of the past, and the list goes on. Instead of learning from our past successes these people throw a childish fit and refuse to work while demanding more pay. It is asinine. If money is important to you find a line of work that pays what you want. Grad school is not that.
Edit: I forgot to mention that these kids withheld students' grades from last semester as leverage. Those students have nothing to do with their compensation but are suffering due to their entitlement. The union for these kids didn't even authorize the strike.
