This might make sense for people with six+ figures sitting in a savings account, but the average person today doesn’t have enough cash to think about earning interest on it. For them, paying off a debt now would be cheaper in the long run. For the most part, at least.
Reddit is only good for massively reposted memes at this point. Any real communities with any semblance of civility are better on Lemmy, in my opinion, thanks to Reddit’s policy of shooting themselves in the foot.
Edit: even with memes, I’ve found Lemmy to be the better option.
