How do interest rates work and why are banks offering me almost nothing?

Interest is rent you pay for borrowing money, or rent the bank pays you for lending them yours. But here's the asymmetry: when you borrow, rates are high. When you lend to them through savings, rates are insulting. A savings account earning 4% sounds good until you realize inflation is eating 3% of it and taxes take another 20% of what's left. You're running to stay still. Why so low? Because banks know most people don't have options. Traditional banks keep rates artificially depressed because they rely on cheap deposits to fund their lending empire. The real money for banks isn't in paying you—it's in lending to people desperately seeking credit. If you must use savings accounts, shop aggressively. Online banks and credit unions often offer 4-5%, though these rates change constantly. But be honest: savings accounts alone won't build wealth. They're for safety and liquidity, not growth. For real returns, you need to understand investments—stocks, bonds—which carry different risks. The rational move? Keep emergency funds liquid in high-yield savings. Put money meant for long-term growth elsewhere. Banks count on your resignation. Don't give it to them.
