Those of us having children are the only ones helping you have all the social welfare programs (pensions and Social Security, etc.) after you stop working.
Ahahaha. First off, those programs are pyramid schemes and unsustainable. Secondly, if those of us who choose not to have kids weren't forced to subsidize you (schools, tax credits / deductions, etc), we could invest it and earn far more than we'd ever potentially see from mismanaged entitlement programs.
The couple decided between them to have the kid, you fucking moron.
Sometimes. More times than not it's the woman saying "We're having a kid or I'm divorcing you and taking everything" or, more commonly, she just stops taking her birth control without telling him and then "Wow, I can't believe this happened!".
You don't want kids? Just as bad - you'll be considered married in CoP if you simply live with her for a long time[1]
Not in the US. Almost all states in the US have eliminated "common law" marriage (though existing ones aren't nullified).
The poor don't WANT to be poor.
True, but most of them also don't want to do the things necessary to NOT be poor (put off enjoying pleasures today for a better quality of life years down the line, work hard in school as a kid so that you can get scholarships and have a good career 10 years later, etc). Everyone's life is a result of the choices that they make. So while they might not want to be poor, their choices have certainly led them there. I say this as someone who grew up poor and had to work full time while taking out a shit ton of loans to get through college and grad school. I spent years working in shitty hourly jobs such as fast food and retail and I can assure you, the lifers there have no desire to put out the effort to achieve anything better - sure, they want the money / nice things of having a better job, but they don't want to put out the effort to obtain that better job.
