Imagine you have a big jar of cookies that you can share. If you give more cookies to everyone, they will have more to eat and be happy, but then you have fewer cookies left for yourself. If you keep fewer cookies, you will have a lot left for yourself, but then some friends might not have enough cookies to eat.
So, lower tax means you keep more cookies for yourself, but poor social security means some kids won’t have enough cookies. But higher tax means you give away more cookies to help everyone, but you have fewer for yourself. It’s like choosing to share more or keep more, and it depends on what makes everyone happiest!
