What factors slow down economic development of US?

Political gridlock is an issue, but otherwise economy is going relatively steady forward, with some of the largest job growth occurring back to back in the last few months. Global issues such as war, energy prices, and trade relations can have effects.

Taxes slow down the growth because tax pays for most of the resources. Also debt because we are missing lots of money and sooner or later you have to pay for that debt this is slowing down the economy
