That argument has been put forward for years, decades even, yet the top teams always hire the top drivers and pay the top money,
it was only in reference to Supply & Demand from the previous poster. To illustrate that driver salaries aren't necessarily governed just by Supply & Demand as on paper it doesn't appear to be the case for eg Mercedes. They aren't paying top dollar to Hamilton because there is a scarcity of top drivers to fill the seat or because without him they wouldn't be winning. Clearly there are additional factors at play.
