I strongly believe that this should be the standard everywhere. Unfortunately most governments won't tell you this, because a few of them are busy building golden temples for their authoritarian leaders, and blowing half of it on cocaine while pretending it's the immigrants' faults
This is but one of many sites which show a breakdown of where our money in the US goes. Having one that breaks down each person's personal contribution would be especially interesting, but a percent is a percent so if 20% of our money collectively goes to X, then 20% of what your paid as an individual will also go to X.
sometimes accessibility and user experience is more important than "its available if you look for it.: 99% of people don't really have time, they have families, jobs, some leisure, cooking, paying bills, visiting family. etc. etc. So it should be easy and the FACT that it isn't easy is purposeful whereas the Australian system is purposefully easy.
I don't disagree with your sentiment, but again, it IS easy. It took me less than 10 seconds to find the link I provided. Sure, make it even easier still by including it with every tax return, but let's not kid ourselves - this shit is incredibly easy but average taxpayers just don't want to bother.
I would argue average taxpayers don't know it exists and a ton of them, particularly older ones have a very hard time with technology. I've had to show my mother in law how to get a url from her phone to her desk top, I've explained what the read mode means in Firefox, and numerous other things. Easy for you doesn't mean easy for everyone.
Not only this, I think this should be selectable by taxpayers before they pay taxes so they can customize the amount that goes to each category. This would be the true democratic way of doing it.
So, for example, based on your salary you need to pay 20k in taxes. You'd then select how much you want to go into Transportation, Healthcare, defense, education, etc.
This would quickly force the government agencies to work for their money.
This wouldn't be truely democratic. It would rather be just like donations. Government spending works, because it's all out into the same basket. If it weren't, then rich taxpayers would move the movey to projects they want - and as would have very little old-age welfare, because they don't pay much taxes anymk6and every group in society would put the money into their projects.
This is a poor take, a few to vote is not the easy to go about this. Even owing taxes shouldn't bar someone from voting as voting is about being represented and everyone deserves representation. Even hardened criminals.
