Inactivity fees are bullshit. The marginal cost of generating a periodic (edit: electronic) statement for an inactive account is essentially zero anymore, as is the cost of storage.

While I'm at it, minimum balances on plain old checking and savings accounts are also bullshit. All of these things are just excuses to take money away from people, primarily those on the poorer end of the wealth/income spectrum, who are the least able to afford it.
