There are also a lot of other ways companies get much more favorable tax treatment than people — for one thing just very fundamentally, they are taxed on profits but people are taxed on revenues, with no ability to deduct most major costs like paying rent or healthcare bills below a very high cutoff.
Kind of a tangent here but I can’t help thinking about this discrepancy when I hear about ISAs, and how people should be able to use the funding methods that companies do like selling shares in themselves. You can be a company but without any of the favorable treatment!
