Is this an example of bad etiquette at the workplace? It's about the rebate

[anon in idaho]

checks the US government is giving out this summer. Almost of all of my fellow Wal-Mart co-workers cannot wait to get their rebate checks from the US government this summer.It's all that they talk about during breaks and lunch.

Meanwhile, due to Social Security making a error with my disabitlies and health problems(testicular cancer, ashberger's syndrome etc, a new problem is happening now )
, they claim I owe them several thousand of dollars. That means that each and every year I do tax's and get a return they get my return money!! I was about to tell them not everyone is lucky to to get those checks and that they should be thankful that they are not in my shoes or someone else's like mine.

Is this a example of bad etiquette in the workplace? What if I wrote a letter to the newspaper and they read my letter telling how not everyone is get those rebates. Besides most people aren't even aware that these rebate check are only a temp fix and they US is going to get more deeper in the red because of these checks
I just walk out of the break room since it's make me so pissed that they are getting them and I'm not. Besides my health problems might be getting worse. I wish that people would stop and realize that not everyone is getting those checks, especially that need it like a testicular cancer survivor and I might have to a operation or more doctor's look into a problem with my head.It's affecting my whole body.My doctor's have no idea on what my strange bump is on my head. I've had two CAT scans, a biopsy and a bone scan latter this week.
