Uh...because the market is imbalanced and will forever be in favor of the employer, when it comes to wages. Do you think that's going to change when this wave of automation hits?
The market for which jobs is imbalanced? You are applying a hasty generalization that assumes demand for all jobs is relatively the same across industries, let alone regions or periods of time which is false. Depending on the job, depending on the location and period of time certain jobs will be more in demand then others jobs based issues of supply and demand for employees and employers for a given job and the value of the labor it offers the employer and the end customer.
You argue that some businesses have razor thin margins and think they wouldn't cope with price increases, how long before that low wage drops before people are unable to cope? More importantly, how do you think businesses will fare when their customers can't afford their products?
There are some business which do have razor thin margins especially retail business which typically depend on selling products in large volumes and/or have goods which require high turn over rates to justify keeping them on their floor space for various reasons (e.g. expiration dates on certain goods).
If you think businesses like supermarkets or retail chains can survive seeing their labor costs increase without justifiable cause or without there being consequences then you are mistaken. Businesses which must generate a profit to survive have to justify their costs and will always seek to cut costs wherever and whenever they can in order maintain their competitiveness with their competition in a given industry, especially in the retail or service sector related industries.
If that means hiring less, then they will hire less, if that means out-sourcing then they will outsource, if that means increasing the adoption of automation then so be it, if that means cutting benefits to their employees then that is what they will do, etc. They will do this so that they are able to stay competitive with the prices of their goods and services so that will not lose customers to a competitor because they were forced to raise their prices which is the very last thing any business which relies on razor thin margins would like to see occur.
And more food for thought; if people were paid more do you think the quality of goods might go up? Would goods increase in quality if people were paid less (ie via inflation, ie removing minimum wage, ie letting the market have free reign)?
Improvements in the quality of goods and services occurs as result of competition in a market forcing competitors to compete against each other and use any advantage they can gain to earn customers. Sometimes that competition pushes prices down, sometimes it pushes the quality seen in the marketplace to go up, etc but there is no real correlation between higher wages and higher quality goods and services when there is no benefit of paying more for a wage then what the market is willing to bare and when the outcome of producing a product or service remains relatively unchanged no matter how much more you force employers to pay. In other words simply paying people more money to make a assemble a pre-cooked burger won't make that burger taste any better for the consumers so forcing wages up for those types of jobs has no real justification for businesses whose biggest cost related to the wages they pay their employees.
]Do you even care about quality or do you think that a quality product might be an edge American businesses have over their foreign (ie Chinese) counter parts? Do you think Americans would pay for quality if they could afford it?
The quality of a product is certainly a factor for many consumers but the perceived value of the product and its price is what in the end determines whether or not that price paid for the quality delivered is justified in terms of the price for someone is willing to pay for a given product or service and the value they place on its quality.
In other words while some people may love the perceived quality and value provided by consumer electronic goods producer such as Apple others may not value it as much as the affordable prices provide by a rival company such as Samsung. Of whom produces a competing products in some cases at reduced cost compared to the premium prices charged by Apple on its products simply because they are made by Apple itself.
Without seeing your response I'd assume you are all for cheap, crappy, products, so long as American companies can make a profit, right? Fuck actual Americans, who are currently working low paying jobs! Profit before people! Am I right?
I shop to get the most bang for my buck because my time and money has a value to me personally that I consider to be important. Now maybe you do not value the money you earn or the time you spent earning it but I certainly do and how I base my purchasing decisions is very much based on the perceived value view a good or service as delivering to me in relation to what I am willing to spend to acquire it and how much I really want to have it versus how much I do without it.
