The US government losing money/wealth is irrelevant to the US corporations in control. As long as the military industrial complex profits from these wars (and they do), the US government can continue to lose money, accumulate more debt, raise taxes on the non-wealthy, and cut domestic programs. I agree that we, the US citizens and the US government, are losing more than we are gaining with these wars, but the wars are not for our benefit. The wars are for the benefit of those that profit from them.
Also, the US is known for not treating our veterans well when they return from wars. We are known for the worst health care (if you would call it that) in the modern western world. We have the money/wealth to afford the best health care for our people, especially our veterans, yet we have a required insurrance middle-man system designed to minimize benefits for the citizen in order to maximize profitability (which also maximizes suffering).
The negatives that you described are either irrelevant or even desireable (for profitability) to the people in power.
I’m not discounting the other things that you said (obviously China and Russia are authoritarian nightmares and the region is currently very unstable), but you really aren’t seeing the whole picture of the US based on this question that you asked. I think you underestimate our evils here in the USA.
