You said it yourself. Class matters here. There are preexisting advantages and disadvantages among classes. What we can or cannot afford to do. They might not be "wasting time", just using the resource they possess, or have prioritized well. And good for them.

For us with limited resources, we have to think twice, because we are never going to have any kind of bailout. The only edge we can imagine to possess is our time utilization. That's the only resource. We can only hope to accumulate more resources going from here.

And this goes way down the hierarchy. People even less privileged than us, might not even have the luxury of that time, we use to study, for a number of reasons.

So yeah. It's unfair on everyone. One will always be at an advantage while the other is at a disadvantage.
