Why is diagnosis/assessment such an access issue in America and elsewhere?

Like, if its nots public health system its obviusly price-gated for obvious reasons (it can be a commodity or boutique diagnosis for the rich and connected to get their sweet-sweet pharma speed)

I take arguably the sweetest or 2^nd sweetest of that sweet-sweet pharma speed on prescription so lets not get into the the whole speed semantics for those of us otherwise inclinced

Edit: some advice- skip your first appointment on accident. It seems counterintutitive but its actually completely intuitive and expected for an actual ADHD person. If I was a psychiatrist I woupd almpst expect or come to expect people who end up diagnosed to do that haha
