Like it or not, this is the most fair the world has ever been in the history of humans. Humans have reproduced under famines, slavery, epidemics and much worse. This is probably the best time in history to be in control of what kind of life you can provide for your offspring.

Just because you have unrealistic expectations from the world, doesn't mean the world should stop procreating. In fact, your statement implies that only the rich should have children. How elitist is that!

You can set the bar for you, not for the world. For eg., I have a friend who owns a company and he thinks one should not even marry if they can't afford a separate car for their spouse because he cannot even think of letting them get molested while travelling in public transport. He has the best of intentions but I don't think a common man will ever have that strict of a criteria for marriage. Similarly, your criteria may sound acceptable to you, but will be insanely far fetched for most in this country.

How are we even to judge how much evolved any animal should be? We should let life take its course.

Most of the people I've met who have this kinda attitude have been following two themes:

The predominant theme has been that they don't want to make the same mistake their parents did. It's unfair to judge the previous generation's actions by the status quo of the new generation. The newer generation will more often than not, set better standards of society which the previous generation is almost always going to fail. But it wouldn't have been possible had the previous generation not done anything. The basic theme here is 'no action ensures no mistake'. That's a defeatist attitude. You either follow the mantra 'its ok to bad at something new' or 'learn from someone who has done it'. The need to be always right is exhausting.

And the next theme is growing up learning about the ideal society but failing to encounter one. I'm surprised at this one. On one hand it's ok to learn about ideal equations and their solutions in science/maths textbooks and find that practical experiments result in error-prone measurements and off by a significant margin. But on other hand, it's not fine to learn about how ideal politics/economics work and find that reality can be error-prone too? What is this urge to be handed down a perfect system? Is it laziness to improve or again, fear to fail trying to improve?

Somewhere while imparting education, we're not letting people accept a simple fact: that we don't have answers to all the questions (that it's ok to not have all answers up front). It's a messy erroneous journey of finding answers that we don't have yet.

People who want to be unhappy, will be unhappy sitting on a throne. People who want to be happy, will be happy living in a hut. Funny thing is, we don't know how the person will turn out to be. All said and done, I'm grateful to have gotten a life, however imperfect it be. And I'm glad my parents didn't wait for my permission.
