You're a smarter man than I for being able to figure that out from a comment which merely states that the solution to poverty is just getting a job. I think political discourse has broken us in many ways. This is another symptom, where we lose any sense of empathy or compassion out of some sort of "economic policy". Believing that SNAP gets abused, won't solve poverty, or whatever your political position is, doesn't necessitate being so callous and cavalier to people's hardships and suffering.
Look at the context of his comment. The first tweeter says he's heard that people may get shamed by using EBT cards, so we should just give them cash. The second tweeter responds, "Everything else about SNAP benefits is set up to shame and fail people. Everything."
I don't believe OP was trying to belittle the poor or oversimplify the issue by telling the poor to "just get a job." The comment was made in response to privileged liberals pontificating on the struggles of using a SNAP card (which, ironically, has actually made it easier than it has ever been to use those benefits). Again, I don't agree with the language used, but I don't believe there was ill will intended towards the less-fortunate.
