If I was selling bonds, the first thing I would do is give everybody a free hat
It's clear from historical pictograhical evidence that bond buyers wear hats.
It wouldn't hurt to put out a few false news reports that shampoo and sun rays damage the scalp and everybody just to be safe should wear a hat when going outside.
Once you got them all wearing hats it should be easy to sell them bonds.
I mean, that's how they did it in the past.
