What Even Is Economics? The Secret Rulebook Behind Every Choice You Make

Mia’s finger hovered over her phone screen, the bright red “Add to Cart” button for the Sony noise-cancelling headphones pulsing like a dare. The envelope of birthday cash from her grandma—200 crisp dollars tucked inside a handwritten card dotted with doodles of lemons, her favorite snack—sat on her desk next to the half-empty iced tea she’d made ten minutes prior, the ice already melting into the glass. To her left, a notification popped up from Lila, her best friend of three years: “FESTIVAL TICKETS ARE ALMOST SOLD OUT!!! We have 2 hours to decide if we’re going or not 🥺🎸” The message came with a screenshot of the festival lineup: her favorite indie band was headlining, the same band she’d been stanning since she was 12, the one she’d forced Lila to listen to on repeat during their 7th grade sleepover.

Her walls were plastered with that band’s posters, their lyrics scrawled in gel pen across the margins of her math notebook, and she’d already saved up $40 from selling handmade friendship bracelets at school for the festival’s limited-edition band merch. But the headphones? She’d been begging

Mia’s finger hovered over her phone screen, the bright red “Add to Cart” button for the Sony noise-cancelling headphones pulsing like a dare. The envelope of birthday cash from her grandma—200 crisp dollars tucked inside a handwritten card dotted with doodles of lemons, her favorite snack—sat on her desk next to the half-empty iced tea she’d made ten minutes prior, the ice already melting into the glass. To her left, a notification popped up from Lila, her best friend of three years: “FESTIVAL TICKETS ARE ALMOST SOLD OUT!!! We have 2 hours to decide if we’re going or not 🥺🎸” The message came with a screenshot of the festival lineup: her favorite indie band was headlining, the same band she’d been stanning since she was 12, the one she’d forced Lila to listen to on repeat during their 7th grade sleepover, until Lila’s mom came upstairs and threatened to take away their popcorn if they didn’t turn the music down.

Her walls were plastered with that band’s posters, their lyrics scrawled in gel pen across the margins of her math notebook, and she’d already saved up $40 from selling handmade friendship bracelets at school for the festival’s limited-edition band merch. But the headphones? She’d been begging her parents for them for six months, ever since her old Apple EarPods gave up the ghost mid-podcast in the middle of math class last semester, leaving her sitting there with only one ear working, nodding along to Mr. Henderson’s lecture on quadratic equations while the other ear blared the true crime podcast she’d been obsessed with, earning her a very confused look from the teacher and a detention for “not paying attention” that she still insists was unfair. The new ones were on sale for $150, 30% off the regular price, and the sale ended in 2 hours—same as the festival ticket deadline.

She tapped “Add to Cart” so fast her thumb slipped, then immediately tapped “Remove” before the confirmation page could even load. She did it three times, her breath catching a little when the third removal made the little cart icon on the top of the screen shake, like it was judging her. She scrolled back through her camera roll, stopping at a photo from last summer: her and Lila at the beach, Lila’s face covered in sand, both of them holding melted ice pops, grinning so wide their cheeks hurt. That was the summer she’d skipped the beach trip to buy those limited-edition Nikes she’d been begging for—they’d been 40% off at the outlet mall, and she’d used all her birthday and Christmas money from the year before to buy them. They’d lasted one wear before the sole started peeling, and now they sat in the back of her closet, too beat up to even donate. But that beach photo? She’d printed it out and taped it to her laptop cover, and every time she felt stressed about school, she looked at it and laughed.

Lila sent another message, this one a voice note that crackled a little through her phone speaker: “Mia, it’s totally okay if you want the headphones! I can just go with my cousin, it’s no big deal. I know you’ve been wanting those for forever.” Mia’s throat tightened a little. She knew Lila was lying—Lila had been talking about this festival nonstop for three months, ever since she saw the lineup pop up on TikTok. She’d saved up $100 from her allowance and birthday money, plus every quarter she’d found in couch cushions and every $5 her grandma gave her for good grades, all stored in a piggy bank shaped like a cat that she refused to break open even when her mom told her the festival was “just a bunch of loud noise.” If Mia bailed, Lila would either have to go with her cousin who hated the band and would spend the whole time complaining about the crowd, or she’d have to stay home and watch Mia post all her stories from the festival, and that would be way worse.

Mia’s social studies teacher, Mr. Torres, had mentioned something last week that popped into her head out of nowhere: “Economics isn’t about stock markets or GDP. It’s the study of how people make choices when they don’t have enough of what they want.” She’d been passing notes to Lila at the time, so she’d only caught half the sentence, but now it clicked. She’d always thought economics was that boring thing her dad watched on
