OP called it
All the potential gains missed out on as opposed to just saving is ridiculous. OP made this in 2019. If the average person would have put that 1200 dollar stimulus into a random popular invest lets say BTC they would have 10k(9830k) right now in less than a year.
If they would have saved that their buying power most likely would have dropped some within that time.
With the argument being SAVING vs INVESTING.
OP didn't call anything. it's his opinion and the way he manages him money, he is more risky than me.
I am good financially, and I still have my 10k emergency fund, and I'll never touch it. Yes, I could invest it but I'm not going to.
There are some things you can't pay with a credit card, like rents or mortgage, but if you want to do a cash advance and risk 20% interest on that with no clear future that you'll be rebounding your source of income, go ahead and do that.
Again just my opinion, just b/c the stock market hasn't crashed doesn't mean it won't, just because things have happened before doesn't mean they won't, there's infinite possibilities for the future. Just have something in case shyt hits the fan.
