Back in the day as a factory worker in 1965 3to 4 dollars an hour in calif.

The cast of The Wager and the Wage Earners - 1911 includes: William Bechtel Robert Conness as Van Bibber Mary Fuller
the average wage is 95,000
As per stats of federal budget of 2014-15, the minimum wage/salary has been declared Rs. 11,000 per month for workers of all sorts. If we convert this amount in US$ it is equivalent to US$ 105 per month. Considering this minimum wage the average wage can be guessed which I assume is in between US$ 105 to US$ 150.
