The US occasionally has mayors & governors who spitefully or corruptly trap their successors contractually in long-term commitments with private parties which are obviously bad financial decisions.

I argue that we have a reasonableness standard we can apply here - "Lack of consideration" is what might void a contract indenturing a 20 year old idiot in an unpaid MLM scheme.

Consideration of the public is a factor.

> "Chicago's 2008 parking meter deal, a 75-year, $1.16 billion lease to private investors, is widely criticized as a lopsided, "worst practice" agreement. The deal, pushed through in 72 hours under Mayor Daley, forces the city to pay "true-up" fees for lost revenue, resulting in over $2 billion in revenue for investors [so far] while the city continues to settle costly disputes."
