If you want to use a the software analogy it's advocating for using a simple monolith you can maintain with <10 people vs a distributed micro service architecture you're working on with hundreds of devs and has countless non essential features which can break the spirit of the system if used in conjunction.
Drafting a simple tax system is easy. The thing that would be borderline impossible is getting it passed into law because of vested interests
I’m actually in favor of removing all charity exemptions too. They are just used by rich people to spend our money (the taxes they owe) on pet projects depriving everybody of that income.
I'm all for removing loopholes where it's possible. However
- It's not "our money". It's money that, we a society, feel validated in taking from members of our society to pay for things that make our society better. But it is, in no way, "our money". We're taking it from people, at force, because we believe it's worth it.
- The only taxes that are "owed" are the ones defined by the rules (laws); pretty much by definition. If the rule doesn't say they owe it, then they don't owe it.
the people with money prefer being able to employ someone to essentially skip paying altogether.
But if they couldn't - because there are no exceptions and loopholes - society would be better off.
