I would have thought that the extra price for LH grips\LH stocks\LH actions is down to paying for the tooling to make it and then for every 9 RH guns sold only 1 LH gun will be sold. This is assuming left handers are equally attracted to shooting as right handers.
As you know, prices go down with volume manufacturing and vice versa.
Left handers make up only 10% of the population. The top 10% mind
Yes, I'm left handed (but shoot right handed )
