> It was really was a disaster for whip companies, carriage companies and saddle makers, though, disruption didn’t proliferate as quickly then as it does today.
I'm not contending that.
I'm saying (as far as I can determine) that cars sales alone in the US today is around 4% of the GDP. That doesn't count all the businesses employed in car manufacturing, all the businesses employed by the distribution network, by auto maintenance, ancilliary auto services (insurance, car washes, cosmetic finishing, upgrades, motorsport, etc).
My argument is that the demise of buggy whip manufacturers was accompanied by a significant expansion of employment. The replacement required much more labour than the thing it replaced.
If, at the time, buggy whip/saddlery/etc sales, distribution and manufacture collectively were the largest employers of labour, then the buggy whip argument makes sense.
I don't think it was.
