I don't know why you're being downvoted here. A huge amount of 'financial advice' boils down to 'stop being poor,' which is to say it's about what to do with your economic surplus rather than what to do if you don't have one and aren't long on avocado toast.
I didn't downvote them, but I am genuinely curious to hear from people who "can't save money", and try to understand why that's the case. My assumption is that a large percent of them are spending way more than they need to, but that could easily be an incorrect stereotype.
