My hypothesis about this for a long time has been stimulants help everyone be more productive (with some tradeoffs) and ADHD is kind of a weakly differentiated diagnosis that could apply to most people.
Probably something like this was lost when people stopped smoking, obviously beneficial for health - but a huge amount of the public was taking stimulants regularly via nicotine until relatively recently.
