I know how to get 500 white liberal suburbanite young males to pay me $10 per month. They have the money and they love to spend it on tech and gadgetry that makes their lives even more comfortable. But single house mothers? Poor Romanians? How would I even get them to pay me half a cent.
In my mind, all these people really want and need is money, they are a receivers market, not a spenders market. I imagine them needing to spend money on food, education, housing and entertainment. All incredibly tough nuts to crack. If you even succeed at coming up with something those people want to spend money on, you're directly competing with the poor people dominators like Coca Cola.
The IT startup scene we're in is just a kids playground, do we really believe someone like Mark Zuckerberg could survive in the business of making money off poor people (directly)?
