Thinking out loud here... for real wages to go up, real prices for services and goods must go up, else companies go out of business. Rising interest rates discourage companies from making capital purchases on credit (which they all do). To service higher debt, companies need to raise prices for services and goods. Which reduces purchasing power... And people who miss basic economic understanding scream for higher real wages and increases in purchasing power. On another note, are student loans typically fixed or variable interest rates?
