I don't know why you're jumping to that conclusion. Yes, it's possible they just received a tax refund. But why assume they were receiving EIC? Maybe they got a refund without it. Maybe they just wanted a big TV for the Super Bowl. TVs often go on sale at this time of year. I don't see any reason to presume you know what's going on in those shoppers' wallets.
Because you weren't there to see what I saw through my eyes. I admitted my opinion may be judgemental in that particular circumstance, but I know of several people that use their tax checks to buy purchases such as those. I also know people that work 2-3 weeks out of the year to have just enough income to be able file tax returns and claim EIC.
It is what it is. As I also stated, I don't have a solution... just a general observation. Actually, what I was really thinking at the time is that we should just send our tax money straight to China and cut out the middle man, but that's a whole other thread.
