Answer:
Split labor market
Step-by-step explanation:
The split labour market gives an explanation to the racial discrimination that exist in the labour market. It is where a group of people would receive less salary of face exclusion based on their race or gender, etnicity, etc
It is a form of labour market segmentation and it was proposed by Edna Bonacich.
From what we see here we can see the builder exclude people who are qualified and we can also see other discriminations where he chooses Mexicans because he wants to pay them less.
