Want to pay your fair share?
Want to contribute to society?
Want to do the most good possible a single person can to make society better?
Do a job.
Create a job.
If you have extra, creating opportunities for others is better than any charity and certainly better than a tax.
Outsourcing your contributions to society via charity or government tax is the most inefficient method of doing good. So inefficient it borders on evil.
You can and should do better.
