No, it would depend on the government's capacity to borrow which you (incorrectly) implicitly assume is based on the size of the economy (which you incorrectly assume will grow) REGARDLESS of whether the government gets to tax that economy.
If the ability to borrow is not based on the size of the economy, what's it based on?
Isn't 10% of 10 trillion the same dollar amount as 5% of 20 trillion? Wouldn't the latter be preferred?
