What poor person gets aspiration because of Spacex. A basketball player is cheaper and does a better job inspiring.

The poor cannot afford to run adwords campaigns and can't even get a credit card.

Facebooks ads even more expensive.

The poor are not looking for short term rentals and cannot afford to live in the most expensive cities using airbnb. They live in rundown rent controlled places.

Paypal allows the poor to buy/sell.
