I feel like you're being deliberately obtuse on this thread.
I'll accept that investments aren't savings, they're not as easily accessible etc.
But people who aren't rich have savings so they have something to dip into on a rainy day. They generally put it in a savings account so that it doesn't get spent accidentally, and it earns them a tiny bit more while it's sitting there.
You have that too, you just leave it sat in your current account, because to you it's a miniscule amount to money. Let's say your current account balance never goes below £5k. To you, that's just sat there, it's a miniscule amount of money, but to someone who's scrimped and saved to get that money, it's everything.
For both of you, it's savings. (As in it's money you both own that you've not spent, you've saved it.). For both of you, it's available to use in an emergency.
The money serves the same purpose for both of you, but for the poor person it's everything, and for you it barely matters. If they spend it, they've got nothing for years, if you do, then you'll just build it back up in the next couple of months.
