Why do some jobs pay so much less than others for similar work

I've thought about this for a long time. The gap rarely comes down to the work itself—it comes down to what economists call bargaining power, and what I see as a question of dignity. When you have few alternatives, when you're desperate, when the market knows you are—your wage reflects that vulnerability, not your worth. A cashier and a software engineer may both solve problems all day, but one sits in high demand with options; the other faces a line of equally qualified people behind them. Owners know this. It's not conspiracy—it's arithmetic. But here's what matters: this isn't natural law. It's a choice embedded in how we structure work, credentialing, and opportunity. Some societies compress these gaps through unions, apprenticeships, or stronger safety nets. Others don't. The wage you're offered isn't a measure of your reason or capability. It's a measure of the leverage you hold in that moment. Understanding that difference—between your value and your bargaining position—changes how you approach negotiation, education, and what you're willing to accept.
