"I had to do <thing that sucks>, therefore everybody has to do <thing that sucks>" isn't a great argument, but "you had to do <think that sucks>, but I don't want to so I'm going to make you do <other thing that sucks> so I don't have to" is even worse. It's like forcing someone who just finally managed to rebuild their house after it burned down to share their house with another fire victim for free.
The selfish thinking that people shouldn't get anything for "free" (ie, shifting education burden from taxes to the student) and everyone should be accountable for every dollar is how we got here.
If I just finished paying off my student loans, and debt forgiveness happened, I would be annoyed and a bit jealous. But also happy that those who had their debt forgiven now have more money to do stuff and contribute to the economy. I would truly be happy for them. Why wouldn't I?
(Note: I don't believe debt forgiveness will ever happen)
Why, though? Depending on how the idea of debt relief shakes out, this might be one of those "sometimes life is unfair" moments that you just have to accept and move on as part of living in a society. The alternative is a massive contraction in buying power, which could certainly directly impact your livelihood. Is the spite worth that?
