People go to work to make money. If they’re lucky, they also like they’re work. It’s ok to want more out of work. Work certainly wants more out of you.
Non-profit just means there are no stakeholders, meaning that revenue must be used for the organization's expenses, which includes the compensation of employees and growth. Many non-profits also benefit from tax-exemptions.
Assuming anything more than that about the nature of non-profits is just romantic BS that has nothing to do with reality.
Also, there's nothing wrong with wanting to make a profit.
