You've asked for more context, so here's what I have that is not talked about in the article.
Leading up to 2006-2007 and the financial crisis, these entry level jobs were salaried positions with standard benefits. Obviously this sounds expensive for a company, and there's plenty of arguing around whether this is worthwhile, but arguing won't help build the context.
During the financial crisis, as companies scrambled to cut costs as much as possible, a trend began to emerge. Companies realized that rather than give salaries and benefits for these entry level jobs, they could hire new grads and anyone else unable to find a job to be unpaid interns, doing the some level of work -- sometimes more depending on the person and position. I hope you would agree that not paying people for work is taking advantage of them. This is obviously more extreme than the contract practice talked about in the article. After it became clear companies were taken advantage of the job market to get free work out of desperate people, states began making legislation to make unpaid internships illegal. Here in California, it is illegal to not pay an intern if their work contributes to the business in any way.
Now that businesses can no longer get free work, they have reacted by filling these positions with hourly contractors who get no benefits whatsoever, no PTO, no sick days, nothing. Salaries for these contractors are often very low. 25-35k a year based on the hourly work. Salaries aren't being dictated by the value of the work the employee provides the company, but by the difficulty in getting (and really going through the process of finding a new job, possibly relocating, etc.) employment elsewhere.
The contrast between these positions 6-7 years ago and these positions now is why people say (feel) they are exploitative.
False. I do not know why you seem intent on being invective and assuming bad faith. I have never once proclaimed any superior understanding of economics, and in fact, have specifically stated the contrary on more than one occasion here at HN.
I simply don't see anything exploitative in hiring people for a fixed amount of time, for a certain amount of money, so long as the terms of both are freely negotiated up front and do not violate the terms of the law, and are not broken through deceit.
Thank you for the background on the rest. The point you made about California law though, is actually federal. The US Department of Labor sets the terms on what constitutes a valid internship, and the last I checked, California has no specific provisions above or beyond that. If you're referring to the recently decided Searchlight case, that was decided that the specific behavior was exploitative, not that internships are in general, where they abide the terms of the Department of Labor.
So yes, it may have been a contract that they 'voluntarily' agreed to for a wage they 'voluntarily' agreed to, but that doesn't mean it's not a shitty position, and we should try to do better, as a society.
Like I said though, if that's the case, it's either outside the scope of this article, or I just missed it. Is that indeed the case, that Amazon is paying exploitative wages for these positions?
As for my 'personal' judgement on what is fair, I always defer to those entering the terms of the contract, so long as those contracts abide by law. If you offer me $10 an hour to do something I might ordinarily charge $100 for, and I accept that $10 an hour, and the $10 an hour does not break any law, then to me, that is fair. I am by no means authoritative on the subject though, so I appreciate any insight you may have.
1) The general (non-Marxist) idea is not that 'the market price is unfair, so we should set different prices ourselves', but rather that the market isn't magic, and does not appear ex nihilo, but is impacted by many things. Some of those things (such as law about hiring, firing, welfare, safety, and so on) can materially affect the negotiation in a way that is patently not fair. For example, if unions had the kinds of powers some ascribe to them (ability to set wages however high they wanted with all staff being unfirable no matter what they did, with employers being powerless slaves) that would be obviously unfair. The power dynamic in many countries (including the US) is roughly that slanted at the moment, but in favour of employers rather than employees - in the US, for example, this is the effect of things like no cause firing, binding arbitration agreements, 'temp' positions and 'internships' being allowed to be offered in place of actual jobs, no real socialised healthcare, limited unemployment insurance in most states, low minimum wages, no 'union shops' in most states, anti union laws, limited occupational health and safetly laws in many states, and so on. So, to make things 'fair', these things have to be fixed - then the market will be 'fair'.
2) The general (Marxist) idea is not that 'the market price is unfair, so we should set different prices ourselves', but rather that capitalist-worker relationships are always unfair and exploitative due to the worker always having to sell their labour for wages, rather than capital, where the capitalist simply gains more money through the actions of capital - neatly setting up a coercive power structure. The (tl;dr version of the) Marxist response is not that this means that we have to set 'better' or 'fairer' levels for wages, but that we have to destroy capitalism and abolish wage slavery.
Here you have to define what "fair" means. One of the definitions would be using extra-market coercion to influence the price - see unions example - is not fair, since it uses forceful coercion to benefit one side. However, unions often claim they need the coercion to reach "fair" prices since otherwise it is "unfair". So what is "fair" here? How you find out if voluntary agreement of two people is "fair" or not?
>>>> we have to destroy capitalism and abolish wage slavery.
Since the only other alternative that we've seen so far is non-wage slavery (at least until we find enough people that agree to work for free that we can create non-scarcity economy) this makes this definition of "fair" rather unappealing. The problem here is that voluntary structures tend to become markets, and calling non-voluntary arrangements "fair" has to rely on notion of fairness of those who apply coercion to support the non-voluntary nature, which very soon devolves into very peculiar understanding of "fairness".
