That's more a commentary on the country they had vs the one we have. My dad at 30 (1981) upgraded from a 2-bed at Block 60 to a 3-bed at Block 4, Amuwo-Odofin Housing Estate, which was then a brand spanking new residential development built by the government for Festac '77.

In other words, he had access to high quality, genuinely affordable social housing that enabled him to save more of his mid-level civil service salary and eventually start building his 1st house just 5 years later, also at Festac.
Our generation has absolutely nothing.

If you're lucky enough to even have the income to be married at 30 - let alone have a child - except you want to live in a Lagos slum, you need nothing less than N1.5m minimum (nearly 5x yearly national minimum wage) for just rent.

Our parents literally lived at places like 1004 Estate, Victoria Island for as little as N200,000/year.
Until as recently as the early 2000s, by the way.
We've been dreadfully shortchanged, which is why I always find it weird when people ask "why are you angry?"
