fair enough.
Being capped at 20k is hardly an amount to sneeze at, considering
in the event of a bank collapse WITHOUT such a safety net in place.
Not even a single cent is "refundable", and especially so critical
when the elderly is concerned whom most have worked for most of
their lives.
Furthermore, the existence of the Deposit Insurance Act is
predominately established to bequeath confidence and assurance to
the average depositor, thus imbuing confidence in the Banking
industry,which serves as the critical pillar to the entire nation's
economy, as a whole. Judging the Deposit Insurance Act based on its
"low cap" and deeming it "hardly any consolation" does not do it
any service at all.
if U are taking the "its better than nothing" stand...then
yeah...U are right. 
confidence and assurance?might be...but I dont feel it.
