[vugihxqi] Market failure in debit card fees

The problem with debit card fees is not with the first banking charging a fee, but with other banks following suit at the SAME fee value.

Instead, what should happen is that if one bank charges a $5 fee, the next bank should charge $4.99.  Once the first bank sees it is losing customers because of its higher fee, it is forced to lower its fee to $4.98, and so on, triggering a race to the bottom until the fee reaches the proper market price.  Note that fees are charged electronically, so there is no additional cost (e.g., handling actual coins) in fractions of a dollar versus whole dollars.

That banks are agreeing on the same fee suggests implicit collusion and thus market failure, and so should be regulated even if you are a free marketeer.
