As a salary-earning individual, there's very little you can do to actually reduce your taxes by a meaningful amount, let alone down to zero like these corporations can.
It's true you can claim a lot as expense and register zero profits but only when you really don't have money.

So what's the alternative? Prevent people from investing into profitable things?
And it was more to demonstrate, does anyone pay more than they have to? Why do we expect businesses to act differently than how individuals do?
