Easy answer, saving isn't giving you profit, it only gives you the same amount that you can pull out whenever you need it in the future and saving is vulnerable to inflation especially if it's the piggybank kind of savings meanwhile with investing although you're risking the money because it grows or regress depending on the value of the investment but the point of investment is that the savings is growing and giving you a profit so totally agree with prioritizing investment over saving but the only advantage of saving in this comparison is that, you can pull out savings anytime as for investment, either you pull it out prematurely resulting in small profit or loss because you happen to pull out the investment at the time when the value of the investment was tanking or lower than your initial entry to that investment.
