Is violence & acquisition so much a part of USA history we reject a move to peace & prosperity for all?

The USA had relative Peace and Prosperity under Clinton, and Clinton left Bush a surplus budget, yet Bush quickly turned that surplus into 2 expensive wars started under false pretenses, attacking two countries, neither of which declared war on the USA because it was individuals who flew small planes into NYC, not governments of countries, then after Bush said Iraq had weapons of m destruction and has later admitted that was wrong. So really the wars are based on lies, and people are making A LOT of money in these wars, and those people would rather not see that money flow stop even if poor American soldiers and Middle East civilians die violently in pursuit of more and more war for others who don't even enlist to make profit. Is the problem that we are so use to violence and death, and so intent on making money, all's fair in war and pursuit of money, property and Oil?
