Simply the base artifact of modern finance. Why do I need a mortgage? (hint: to supply interest payments to banks AKA the institutors of the world of modern finance)
>* Allows you to protect yourself with health/car/life/home/title/etc insurance
See above.
>* Pays for your highways/stadiums/schools and other public works
"Pays". A meaningless word.
>* Protects your deposits
Only through magic. If deposits are lost, they are merely re-created as modern finance is an arbitrary mathematical construct.
>* Pays for your retirement
"Pays for your retirement"
>* Funds the college fund that paid for your school
"Funds the fund" that "paid". Again, meaningless except insofar as your school depends on magic numbers being circulated.
>* ... Or the student loans that allowed you to attend school
Ah, yes, the loans; again, the foundational unit of modern finance, without which the "world of finance" would be radically different.
>* Supports the global supply chain that brings you your iPhone, stocks the grocery store/your favorite restaurants with food, and puts the clothes on your back.
Supports in name, but is curiously not actually involved in any physical aspect of realizing any of those things.
>* Funds the growth of corporations large and small, giving you the job that allows you to buy an iPhone
"Funds" ... "giving [me] the job"
>* Funds the massive philanthropy expenditures that help those in need everyday
"Funds", because the actual work is done by real people.
>* Pays the pensions of the elderly
I guess the system isn't complete evil.
