Investment is not a basic need for the lower class economic people. Investment is a routine for the middle and upper class economies besides having forward thinking.
The concept of investment for people with a lower class economy is simply saving when there is left over after their basic needs are met.
Although most of those low-class people still tend to meet up or level up more quickly than some so-called middle-class people, The reason is that some middle-class people don't even think of investing; they feel they have a sustainable income, so they may not bother to increase their financial worth. But some of this low class will still strive (because they are not satisfied with the stage they are), so they will have to save up the little they have earned and still invest it in something that will earn a small profit for them even if it's not Bitcoin. There is this saying that "if you can't save when you are earning a small amount, there is likely a possibility that you won't save even if you are earning a huge amount." Saving is a habit that most people don't have, and when you can't save, what will you invest? There is no one who can't invest; it's just to develop the habit of saving and investing.
