Why people will be more unhappy and poor

Humanity has been in constant war since time immemorial. Could we consider why we replace the term "dictator" with "president" and "parliament"? After all, when we go to vote, no one tells us that there will be a war. We bear responsibility for the misinformation we've received. Conflicts don't start that way. Someone is always ready. Alternatively, there may be a vested interest in creating conflicts. With a bare ass, what can someone do? Nothing. So someone paid him and, most importantly, provided him with weapons. In the past two years, almost all countries have increased their arms budgets. What follows is that reducing other features improves the citizen's condition. All other things—education, health care, infrastructure, subsidizing food, and others—have no way to improve. Not to mention research centers that need more money to discover better medicines and everything needed for better living.  It affects almost every family. In a word, the common man has no fault. It's primarily businesses connected to politicians that are responsible for these actions.  I am quite certain that very few people desire to go to war. I don't know what the solution is. But one is upbringing from childhood. Another potential solution could be organizing games similar to the Olympics in a specific location, where individuals with harmful intentions might congregate and engage in violence against one another.  But from year to year, instead of improving the state of the countries, it will get worse. It is not clear; for example, if a small country with a small budget buys a hundred tanks, WHAT IS THE EFFECT?  Five planes or something. Wouldn't it be better to create a single global military organization?  All countries should participate in this organization. If a problem emerges, the specific country should suppress it. However, this is an idealistic view.
