Joey Doughnuts works at Sal’s Automotive. Has for years. Joey got set up with a 401(k). There’s no company match, but he puts away about 6% of his $70,000 a year salary (let’s just make the math easy and assume he never gets a raise — poor kid). At the end of his long and successful career working at the shop, Joey has about $700,000 socked away for retirement.
