This new information would be irrelevant to the author’s main discussion.
Step-by-step explanation:
The writers ' main debate was the shortage of labour and explanations for it. Argument about productivity in the British economy at the end of the day – new information goes against, but would not undermine the core point of the case of the author (labour scarcity in employers and workers ' rights)
A labour shortage is a financial requirement of employers, in its widest definition, which believes that there are inadequate qualified (employers) applicants to meet market demands for jobs with wages that are mostly determined by the employer.
