Which country is best in terms of giving benefits to citizens for tax collected?
It’s kinda hard to answer that since everyone’s experience depends on the country they live in.
But in this context, I think countries with less corruption are more likely to provide better benefits from the taxes they collect.
You can see it in their developing economy, big infrastructure projects, lower unemployment rates, less crime, and better healthcare and education systems.
Definitely each countries differs from one another and so is the aspect of benefits and honestly it's unpredictable to figure out which country is best in doing so. You're right on track that a corruption free country it's one that will likely provide better benefits for it's citizens and that's if the government of that country have taken it upon themselves to render selfless help and assistance to their citizen's unlike the ones with selfish interest that will go on collecting tax but find it hard to allocate ways that will be beneficial to the entire citizens.
