But please do explain this correlation between technology, productivity, and conditions in the workplace.
That's standard economics. Income (or output) is a function of [labour] [capital] and [multifactor productivity] (see
Cobb-Douglas production function). The last term is a catch-all for any improvements in the ability to generate more income/output from the same [labour] and [capital] inputs, so it includes techonological innovation, education (human-capital formation), infrastructure, banking, laws, and other things. Societies grow richer by using some of their income to increase the capital stock, and to provide resourcing to increase the input value of the multifactor productivity term.
As they grow richer, societies can afford more "luxury goods" (I use the
economic definition of this which is
something that you spend a greater share of income on as your income increases). If you are starting from a position of relative poverty, then welfare states, workplace conditions, and--in fact--the myriad factors grouped under multifactor productivity itself,
are mostly luxury goods. That means, if you are a dirt-poor society to start with, you don't have them--because it is of greater marginal value for you and all your fellow citizens to clothe, feed and shelter yourselves.
Thus,
income growth is ultimately the overwhelming major driver of better workplace conditions, as well as better <whole bunch of things>. I have never read anything by any mainstream development economist (Jeff Sachs, William Easterly, Paul Collier, Dani Rodrick, it doesn't matter what political leaning they have) which does not agree with this. Naturally you can call that last addendum an appeal to authority. I prefer it over appeals to ignorance.
My claim is that conditions in the workplace are primarily the result of regulations that oversee conditions in the workplace. I know it's a radical concept.
And it's wrong too. Those regulations--assuming they are welfare-promoting--have next to no likelihood of ever being "afforded" until the society that desires them gets above some threshold income level. You need the growth
first. This is why--for example--efforts to implement such regulation through "factories acts" in countries like Bangladesh tend to be accompanied by large-scale displacement of huge fractions of their (child) labour force into the informal sector.
That doesn't mean I am necessarily opposed to Bangladesh's labour laws. It means you can't simply regulate welfare out of thin air if you can't pay for it.
