Why did the first government not work

The central government couldn't collect taxes to fund its operations. The Confederation relied on the voluntary efforts of the states to send tax money to the central government. Lacking funds, the central government couldn't maintain an effective military or back its own paper currency.

during the 20th century, the role of the vice president has evolved into more of an executive branch position. now, the vice president is usually seen as an integral part of a president's administration and presides over the senate only on ceremonial occasions or when a tie-breaking vote may be needed.
