Agreed, in order to save some money you need to earn some money, only then you'll be able to save a part of it. And saving = earnings, so the more you save is the more you earn!
well that's is clear to everyone, without money you can't save anything, the original topic was assuming that you had money in the first place, to proceed to save a small portion of it is better to invest them imho, you need to calculate the risk and reward for this, if the risk is lower you have found your good investment and you can invest without worry too much, if you end up losing anyway, you will go to another investment with less risk and so on, in the end, seeing that the chances are with you, you will earn money on top of your saving
i think that you need to move you saving to save even more money, leaving them sit under your pillow isn't a good idea imho
