Luke's Lascivious Ludicrously Lesbianic Laws of Logic and Life

Just the last 4 please.

Well, uh, I can help you with the last one.

4) Workers may find getting work more difficult, as employers need to hire fewer, better employees to afford a higher wage.

1) idk, depends on your definition of "category of labor".
2) the cost of living varies greatly in regions, even between states within the US. A low starting salary in California would be considered a premium salary in many other states. Competition also plays a role in wage differences in separate regions as demand for talented individuals can be higher in certain areas.
3) The average cost of part time employees is often significantly lower than the cost of full time employees, especially in fields such as unskilled labor. This is because part time employees do not require company paid benefits such as healthcare. Having several part time employees in place of full time employees also lowers the additional cost of over time.
4) A rise in the minimum wage will likely have both positive and negative impacts. Small employers that may be struggling will likely be hurt by a rise in the minimum wage, and may need to adjust their business strategy, halt plans for expansion, or even lay off some of their workers. Larger companies may have the funds to pay higher wages, but will be resistant to doing so as they hope to continue raising profits. A raise in the minimum wage laws will make the idea of replacing unskilled labor jobs more appealing. Unskilled labor can often be outsourced, automated with robotics, or reinvented in a self-serve fashion.
