Resource management is something that only wizards have to worry about, and not even they really have to worry about it that much after 5E, especially given the abundance of party supplies.
Rly? O_o
How so?
In my Experience, Paladins, Clerics, and Sorcerers spellslots were lost fastest ... and Warlocks obviously, but they also get the back pretty fast.
It may have something to do with fact that Wizards, unlike the others mentioned, can renew some spellslots outside of combat.
Don't know man, I never feel like I have issues with spellslots. In fact, if I feel like a spell isn't worth casting in a given situation I probably just use a ranged attack or something.
As a Warlock, for example, spellslots are used for Hex which is reusable and I just spam Edlritch Blast (its incredibly powerful).
As a Bard, I mostly play support so I mostly have healing and buffing spells with the occasional damage spell, and I use them as needed, and I basically never run out.
As a Cleric, I mostly use my spells for healing, or maybe when I feel like I'm unlucky (missing a lot) I throw a Bless spell around, or if I meet a tough enemy I use a Guiding Bolt, but I mostly use my clerics as meelee attackers who also happen to have some support spells. I usually don't run out of spellslots until I get to the tiefling camp, and I usually get there after clearing the ruins with the skeletons.
Sorcerers and Wizards are the only two classes that run out of spells relatively faster, and sorcerers can turn their sorcery points into spellslots and wizards have Arcane recovery. I usually use my spells strategically, so Gale will be throwing down some Dagger clouds and my Sorcerer will probably be blasting wet enemies with chromatic orbs. If they run out o spell slots I just let them use their crossbows and they are not half bad, and since cantrips also scale, frost bolt and fire bolt are not half bad and they can crit too.
