Me and the wife retire in five and a half years, no mortgage, good pensions, and we are off, don't know where yet, could be Portugal, could be New Zealand, one thing for sure, we ain't staying on this crowded rock being dictated to by the loud mouthed minorities anymore.
Back on topic, two children should be enough in this day and age for any couple, yes couple, as I'm being controversial I don't much believe in single parent families from choice, or at least single parents who have no input and active support by the birth partner, children need a mom and a dad.
For those who think I'm wrong let me say I couldn't care less.
