What if everyone could use magic? In D&D terms, could learn

Goodberry is a level 1 spell, so hunger is not an issue for anyone, ever. This alone has huge implications.

And create water is 0th level. The lowest class never really need for anything. Clean drinking water mean lower rate of disease. You're on your way to a Utopia right there.

>Find Familiar
Kids learn how to summon a pet when they become old enough and have presumably a friend for life
>Longstride / Jump
Sports are way more interesting
>Plant Growth / Druidcraft
Agriculture boom. Being able to double the yield of crops is crazy for advancing a civilization.
>Hold Person
Cops/Guards have an easier job
>Counterspell
Cops/Guards have an easier job sometimes.

Think bigger. No need for crops when goodberry exists. And when there's no reason for crops, there's no need for farmers and peasants. They won't exist as a class.
Middle class (skilled craftsmen) still do, however, since their job can't be made obsolete with 0-3 level spells. Mostly.

I think people would like a bigger food variety

What are the limitations on who knows what? What you said in regard to the rarity of 3rd level spells would seem to imply people don't know all spells. Do people have access to more than one spell list at a time? Do you learn more through study, or is it all innate? Is it hereditary?

Major implications of 0-2nd level spells being commonplace:
-Ready access to clean food and water (as indicated by others above) leading to a huge population boom
-Ready access to healing magic. Even CLW, relative to commoner health totals, means that death due to injury is basically non-existent unless people are killed instantly.
-Everyone is lethal. Assuming your average person is between level 1 and 3, having everyone capable of casting Magic Missile (safe, ranged, requires no aiming, reliable, etc.), everyone is essentially armed with lethal weapons at all times. Imagine every person in your society carried daggers.
-Law enforcement gets way more complicated. Between illusions, disguises, invisibility, enchantments, and so forth, on top of the previously mentioned ubiquitous lethality, law enforcement potentially becomes a pain in the butt. They do get some neat divinations though; Speak With Dead is 3rd level and is helpful for a lot of murders.
-Objective morality. RAW, the various alignment spells indicate morality as an objective force in the world. This potentially has a lot of implications, and Detect Evil in particular is a doozy. Could potentially go the Psycho-Pass route with Detect all over the place, and people who ping Evil (or Chaotic?) being brought in for preemptive therapy. Or nastier stuff, depending on the government.

Prestidigitation can change goodberry taste.
People would make food to feel the textures.

By 5e casting, most of >>55297709 's point still apply, except the last one. Add on:

>Cantrips, being infinitely usable, change everything. Everyone just mage-hands things to themselves. The farmers who do exist (to make textiles and such) abuse Move Earth.
>Anyone can bind a familiar, many summon steeds.
>Anywhere with any amount of security has people with Detect Magic up all the time on guard.
>Counterspell exists and can affect anything in the world, but people who are able to cast it are rare.
