Also presented in Marketing myopia, as a warning against complacency, was Levitt's belief that 'In truth there is no such thing as a growth industry.' (ibid.). There are growth opportunities, which can be created or capitalised on, but those companies which believe they are '...riding some automatic growth escalator invariably descend into stagnation.' (ibid.). The belief that a company is in a growth industry and is therefore secure must never be allowed to overshadow or replace awareness of the need to practise marketing and assert a customer orientation. This is the only route through which a company can hope to achieve sustained expansion.
