But you already knew that. There's no reason to falsey attribute malice to what someone says just to flamebait.
What the person you responded to has pointed out is that a lot of workers do not earn enough to have savings. So waving away loss of income in such situations as just spending some money you might have earned previously is not exactly nice.
I have family members working on the new Vogtle Nuclear Power plants in Georgia. Week to week they never know for sure whether they'll be working 7 days, 3 days, or 0 days. Managers do try to plan work stoppages ahead of time, but it's not always practical or possible and workers know this. Except for the most junior guys everybody understands you need to prepare for stoppages, though that doesn't prevent many from crying foul. Wage workers do have it tough, but it's also true that poor planning skills exacerbate the situation, and all the overtime means you can't really compare the situation to a part-time, minimum wage worker who couldn't save money even if they tried.
