I used to work hard for the Brazilian government and every year I was even more convinced I was just doing things to support big tech companies and make Brazilian social security data to be available for banks, financial institutions and big tech.
Now I am working to a company in Canada and the only thing I care about is keeping my job and my paycheck and I don't give a shit about the company's goals of making profits.
Anyway, doesn't matter which sector you work for, some capitalist will still get richer because of you. At least this is usually the case if you are in one of the STEM professions.
