Selfish and irresponsible
Having children is fine, if you can afford to support them properly yourself and do not expect anyone else to be forced to help you.
The decision to have children is an important one, and should be made taking into consideration all relevant factors. Most people do not think about this decision before making it. There are a large number of individuals of little education and meagre means who have learned only that having children entitles them to leech off others who work for a living.
Any person with an ounce of intelligence, looking at the decision rationally, can choose when they want to have children and how many. If they can look at the world as it is today and see that there are limited resources, then a decision to increase the population by making more than two new people is a reprehensible demonstration of extreme selfishness and irresponsibility.
I may have children one day. When I do I will ensure that decent values are imparted to them, that they receive a fitting eduction, and I will PAY FOR THEIR UPBRINGING MYSELF.
There is no reasonable argument for forcing honest working people to pay for others' children. Such a structure only encourages the expectation of low-life to have everything handed to them on a plate for no effort, and perpetuates this attitude over generations.
