1 in 5 is certainly not uncommon by any reasonable interpretation of the term. 20% of the US is an absolutely massive market many could only dream to begin to address as a customer base. That said, even that is not really all that useful. Anyone who is motivated can get these drugs for around $500-600/mo via programs that exist for the vast majority of the population. That roughly halves the cost comparisons here. Very few folks who want these drugs have zero options other than to pay full retail.
