Modern club design plays a bit of a role IMO.

Most people would do better with shorter clubs and slighly more upright lie angles than the current standard fit.

The reason is that this puts you naturally where both the body, and the club design, want to go (physics)

A big part of the reason a huge majority of golfers setup with a cocked left/right wrist position (clubs too long, too flat).

That too long/flat design adds to the too much 'around' move, which can end up on the elbow plane.

The need to sell new 'longer' designs for clubs each year isn't likely to change, but it is certainly worth considering clubs with shorter shafts to naturally get into a better address position (that which is short enough and upright enough to have level wrist positions naturally at address).
