There may be people with low income who have difficulty saving, but I believe that if they are determined enough, they can still save a little. Just like some people here they say they can't save but they have money to gamble online or they have money to invest in bitcoin. But when it comes to saving, they always give dozens of reasons because they simply want to find a way out of poverty by investing. But they don't know that saving for emergencies is much more important than making high-risk investments.
I do not think so, these days the people who have nearly no money are not people who can save, they are literally making debt to just survive, so the idea of saving to make some money doesn't really come easy for them, it is not that possible at all. We should consider the economy we are in as something that requires drastic change in your life to get enough money, like starting a business maybe or something else.
When I say starting a business many think that I mean like a shop, you rent, you hire employee maybe, you get inventory and many other costs. I do not mean that, just start a website, even something as common and as saturated as a news/blog website, write there 2-3 times a day, for 2-3 years, and eventually it will have enough traffic to sell and make you money.
