Topic:
The following appeared in the editorial section of a local newspaper:
“The inflow of immigrant workers into our community has put a downward pressure on wages. In fact, the average compensation of unskilled labor in our city has declined by nearly 10% over the past 5 years. Therefore, to protect our local economy, it is essential to impose a moratorium on further immigration.”
Response:
The passage's conclusion states that to protect the local economy, the community must impose a moratorium on immigration. The evidence that the passages provides is statistical data for the wages in the community over the past 5 years. It then utilizes some phenomenon that parallels that community's activity in these 5 years to explain the decline in wages. The argument is flawed due to the argument confusing causation with correlation.
The first premise that the passage presents is of the community experiencing an uptick in immigration: "the inflow of immigrant workers into our community". The author infers a cause-and-effect from said increase in immigration, stating that this level of immigration is harming the community's wages. The underlying assumption of this premise is that no other factors are causing such a phenomenon to occur, or to the economy in general.
The second premise of the argument argument justifies the drop in wages due to an influx of new workers into the workforce. The premise further states that "unskilled labor has decline by nearly 10%". This premise assumes that nothing else affects the demand for unskilled labor, such as a demand for higher skilled work.
The conclusion of the passage illustrates a cause-and-effect situation, where the increase in unskilled labor from immigrants is causing the decrease in wages. This conclusion is flawed because the passage does not fully support the conclusion; the passage relies on assumptions that do not support the argument as a whole. The passage should instead conclude that the data collected from the past 5 years has lead to a correlation between the community's decrease in unskilled labor wages to the increasing number of immigrants.
