I believe the answer is: A.Smith knew that the invisible hand of the market was not concerned with the health of the laborer.
The power of invisible hand in the market only care about the power of supply and demand which would determine who will obtain the most wealth. Even if the process could disregard the wellness of many people, as long as the demand is met, consumers wouldn't put too much thought on the laborers.
Stocks directly affected only 4 million out of 120 million people. Indirectly:
-Risky loans hurt banks
-Consumer borrowing
-Bank runs
-Bank failures
-Savings wiped out (Banks failures wiped out peoples saving)
-Cuts in production
-Rise in unemployment
-Further cuts in production
