💵 Cat owners donate more frequently and to a wider variety of causes. This may be linked to higher psychological openness and neuroticism often associated with cat people.

Elites don’t just stash money in tax havens—they strategically choose how and where to hide it. We find three main “secrecy strategies”: 1. Diversify assets across jurisdictions 2. Conceal identity (nominees, bearer shares) 3. Use blacklisted havens despite stigma
