No, it's absolutely not. Our currency isn't backed by anything. It's a con, a ruse, it's not real, and The Fed uses that against everyone.
It's not my opinion, it's what Nixon did to us in 1971. The US defaulted on it's loans, it ran out of money, and we've been indentured to that debt ever since.
You don't believe me, look it up. Seriously look up the difference between money and currency. Ask your bank why you can't exchange your dollars for gold. You used to be able to, you know.
If someone else can control and manipulate the value of your labor by manipulating an entire country's means of exchange, YOU. ARE. NOT. FREE.
Slavery with extra steps.
