You can't meaningfully calculate the budget including social security. This is a trust fund that you get back depending on how much you made and how long you live. And whether the outlays are taxed or not depends on your income at payment.

The whole site would be way more informative if social security was broken out.

Even better if it included how much you and your employer spend on health care, because most people are literally spending more because there is no universal health care.

The only thing useful in the whole thing is how much tax money goes to "defense"
