How do labor unions affect the economy

Labor unions can affect the economy by possibly providing higher wages for its workers, but it will simultaneously lower the profits made by the company, and create fewer jobs. This is because labor unions encourage the benefit of the workers (as the workers join together to fight for better treatment), but it will discourage other companies/businesses from investing in the company. So although it benefits the workers morally, it can negatively affect the success of businesses in the economy.

I believe the answer is social development
social development refers to the discipline that aimed to improve the well-being of individuals when they're interacting with their social groups.
A sense of guilt is really important in social development because it allow us to sympathize with other people and form a close/personal relationship with them.
