I think it's worth listing the things people already pay $50 (or more) for:

-TV / Internet / Phone bundle

-Electricity

-Water

-Car insurance

-Gym memberships (?)

-Daycare

-Food

-Interest (home mortgages / loans etc.)

-Clothes

Almost all of the suggestions in this thread are effectively replacements for one of the existing services in one of the categories above. That means you'd have to beat the incumbents (challenges: investment, infrastructure, partnerships, etc.), or create a new market demand. I love the idea though, keep thinking. "If it were obvious, everyone would be doing it".

Things that come to mind: a personal trainer that is delivered through the internet and scalable? Some kind of 'make my grocery list and just have me pick it up' service? Financial engineering that decreases the interest on a large pool of loans (ha!)?
