The reason why increasing wages for low-level jobs is so important is that it puts upwards pressure on all wages above them as well.

If the lowest paid lowest responsibility job has a wage increase, then any job which requires more from the worker needs to increase their salaries, or people dip out and take the easier job for the same salary.

In reality, the example is usually something like a situation where a highly stressful and highly skilled job is maybe paying $30 per hour and the worker decides to change to a menial job for $25 per hour instead or even less.

Any talk of "worker shortages" is not just a lie, it is a lie born from evil. Born out of the current geriatric ideology of hatred against the youth of your own people, which is dominating in industrial society all over the world.

Any business which cannot pay a good salary for the workers they employ shouldn't be in business in the first place. It is better for the economy that those people work with something else. Especially since a normal worker usually has an output of 5-10 times more than what they are paid, and in efficient sectors even more than that.
