Profit is older than capitalism; capitalism is a particularly egregious form of it, but it is profit itself - intentional inefficiency in the conversion of resources to usable product, for the purpose of benefiting those creating the inefficiency that I refer to.
In theory, something very close to capitalism could exist without profit - with everyone getting back only a fair and appropriate compensation for their part in the process. It’s the 'put in a little and get back infinite returns ’ part that makes capitalism specifically a problem.
