Calculate relative income — Tim Ferriss's reframe from absolute dollars to dollars-per-hour weighted by mobility, autonomy, and time-of-life from The 4-Hour Workweek. Use when the user says "is this raise worth it," "should I take this job," "compare two job offers," "I make $X but I'm miserable," "the new job pays more but," "am I actually rich," "geo arbitrage," or "what's my real hourly rate." Surfaces the freedom math — the number that often shows a $80K consultant in Lisbon is wealthier than a $200K employee in NYC. Pair with /mini-retirement and /dreamlining when comparing across geographies.
