The US has also attempted to do this. However, every attempt has been killed by corporate interests (like Intuit) and politicians (mostly Republicans) and special-interest-groups (conservative anti-tax organizations)
This may be true, but I downvoted your comment because I don't see any sources for the strongly worded assertions made.
If we downvoted every assertion on HN that didn't come with a complete annotated appendix of sources, that would be every comment. Why do you apply this standard to this comment, and not to others?
A googling of something like "intuit lobby irs" will turn up as much info as you care to have about the situation, incidentally.
