[Problems]
Child Custody - Many countries like Japan, India, the Philippines, Sweden, Turkey, Algeria, and Greece almost always automatically grant custody to the mother, regardless of circumstance.
Child Support - I could not find a single country that does child support payments as a flat rate. This means that every country that forces a parent to pay child support payments calculates the amount based off of the paying parent’s income.
Marriage - This is a contract that is defined by the govt, not by the parties involved. Over the years, govt has bastardized the contract to be heavily biased towards one side.
Divorce - The way that the govt imposed marriage contract is defined, divorce incentivizes the lower earning spouse (usually women) to break the marriage contract because they often get to take half of the higher earning spouse’s (usually men) possessions. This happens so often, it has its own nickname “divorce rape.”
Alimony (spousal support payments) - Alimony incentivizes the lower earning spouse (usually women) to break the marriage contract because they get paid for doing so. It is extreme govt over-reach to demand how private money is distributed.
[Solutions]
Child Custody - Both parents must sign a “child-rearing-agreement” that will include the percentage of custody each parent will have. This can be re-negotiated in the future. The only involvement of the govt is to demand that some form of the agreement be signed. Possibly the govt could withhold documentation for the child until the agreement is signed by both parties or something along these lines.
Child Support - This falls under the same “child-rearing-agreement”. If a parent refuses to have anything to do with the child or pay child support, there are no legal consequences unless an agreement has been signed. This is where family or private charities would step in and provide a basic flat-rate allowance to help raise the child. If neither parent wants to raise the child, private charities also step in and provide either adoption services or group homes. For those screaming that a refusing parent should be punished, I would argue that both man and woman have been irresponsible if sex occurs without a child-rearing agreement signed, and irresponsibility of both parties is not a situation for govt to come in and fix. Also, the “child-rearing-agreement” will fall under civil law and so no criminal penalties will result from breach of the contract, there will only be financial penalties (See the “breakdancing dad” drama on YouTube for extreme criminal penalties being used against a dad who is unable to pay).
Marriage - Instead of a govt defined marriage contract, there will be privately authored “non-state-marriage-agreements” and/or “cohabitation-agreements”. This will mostly cover how money and property are divided, if at all, and can also include the child-rearing-agreement as a part of it. There will be no legally recognized marriage outside of this agreement. If 2 people move in together but aren’t responsible enough to sign a cohabitation agreement, this is where family needs to step in and apply pressure to get an agreement signed. The “cohabitation-agreements” can later be re-negotiated into a “non-state-marriage-agreements”.
Divorce - This would be covered under the separation part of the “non-state-marriage-agreement” or the “cohabitation-agreements”.
Alimony - If present at all, this would be covered under the separation part of the “non-state-marriage-agreement” or the “cohabitation-agreements”.
