A worth while investment ?

Today I had my suspicions confirmed as to the true value of money nowadays . While speaking to someone at my bank it was suggested to me that it would be more efficient for me to pay off my credit card with a lump sum from my savings ( due to the low interest rate my savings were receiving and the high one my card was charging me / my credit card 19% and my savings 1% approx. )  Off course once the money had payed off the card it was gone . This didn't seem to register as a problem . Off course the bank would want me to clear the card in one go , wouldn't they ? But then they would loose the interest I would  have payed in the future . It seemed more important to make a short term gain for themselves I guess . Are they gathering in all they can as fast as possible , and does this mean they see trouble ahead ?  Is money only fit for paying off debt ? Is this its new worth ? Does this deal qualify as an investment ?!
