I would suspect that companies do not prefer to hire Indians because they are cheaper but because

1 Indians prefer to hire other Indians

2 Indians who are already working prefer to have Indian coworkers

3 They are not White so they can cause trouble for White people

4 They can count them towards affirmative action or DEI quotas

5 India is loyal to Israel

6 We should ask if Indians are more likely to vote Democrat

7 We should ask if Hindu culture promotes tolerance over harsh truth
