I'm not saying saving 10% is bad. It may be good enough to retire depending on when you start out. But it won't take you out of the middle class.
For most developers in my city, 10% means saving $7-10K a year.
To become a more sophisticated investor, you'll need to start reading books (uh-oh!) on investing, accounting, and business.
That wasn't in dispute. The issue in contention is moving out of the middle class.
Having $1.3 million in retirement when you're 65 puts you squarely in the middle class, if you go by the 4% withdrawal rate.

It turns out that your local thrift store is a great place for both of those cheap. I bought a very nice sound system for about $40 including speakers, one that a couple decades ago would have cost a couple grand. You can get real nice flat panel TVs from the pawn shop for next to nothing, too, as well as computer equipment.
