What is the mentality of all bosses when recruiting employees?

Personally, most bosses ask employees to bring profits and resources to the enterprise, and it is best to do anything, and then the salary can't be so high that they can't recruit employees. But what is said here is only most, not all, because there are indeed some wise bosses who are very kind to their employees. However, personally, it is difficult for bosses who take advantage of employees to recruit good employees in the end.
