In your opinion has the united states been a leader in the global economy in recent decades? explain your reasoning.?

The US has had the leading economy since it has a controlled economy and it manages its money but the US's economy is going to start going down if they don't stop wasting/spending money.

but whats the question? ?

explanation:

in mcculloch v. maryland (1819) the supreme court ruled that congress had implied powers under the necessary and proper clause of article i, section 8 of the constitution to create the second bank of the united states and that the state of maryland lacked the power to tax the bank.

gibbons v. ogden, (1824), was a landmark decision in which the supreme court of the united states held that the power to regulate interstate commerce, granted to congress by the commerce clause of the united states constitution, encompassed the power to regulate navigation.
