You: I never said "not showing up at work".
Neither did I. If you want to argue against someone, inventing phrases I could have said and arguing against those when anyone can read that I didn't say them is pretty obviously wrong, isn't it? In fact, I said the opposite: "being expected to work".
We've pointed out easy methods by which someone could have little money for reasons other than not being able to handle it. If someone's been employed at a high-paying job for a few years and still can't withstand a month or two without pay, then they're indeed less sympathetic, though it still isn't acceptable. The system doesn't withhold payments only for those who have no pressing obligations and plenty of opportunity to have built up savings. It will affect someone who just started a job or those employed at things where the salary is low just as well as to tenured senior ATC agents. If someone was offered a higher salary for being willing to move and has just done so before the gap starts, they incurred the costs of a move and those of living in an expensive place and have not had the opportunity to build up that buffer you're castigating them for not having. For someone who complains about the US so much, you seem to have embodied the negative stereotype Americans are often accused (sometimes accurately) of having that your misfortune is a failure of personal responsibility regardless of the circumstances.
And when they are paid better, then I do expect that people can deal with a gap in salary, but that doesn't mean they should have to. I'm not sure what contrast you were trying to make between public and private employment and would welcome an expansion of that point. One major difference is that if my employer decides they're going to not pay for some time, even though I have plenty of savings and could withstand that, they would need to present a pretty good explanation of this for me to voluntarily agree to it, and it would have to be voluntary because doing so involuntarily is either wage theft or insolvency. Telling me to keep working and they'll pay me if and when they feel like it and I'll be punished if I complain is so abnormal and unacceptable that it's actually a crime, and one for which the penalties are much higher than any interest rate.
