As I got older I realised this wasn't so. A lot of the time reason didn't come into it at all and all sorts of irrational considerations came into play.
I optimistically thought poverty could be ended easily if governments took more money from the wealthy and gave it to the poor.
Eventually it dawned on me that it wasn't so simple. Politicians were reluctant to tax the wealthy (especially if they were wealthy themselves). Some thought the poor should find their own way out of poverty and shouldn't need government help. Others thought the supposed poor weren't really poor at all and had hidden sources of income. And so on.
Likewise building more homes or increasing people's salaries or dealing with greedy landlords. What seems like the obvious solution is stymied by irrational objections that prevent any real progress.
Nowadays I tend to be a bit cynical about any grand plans announced by politicians. Instantly I envisage a flood of half-baked protests likely to stall those grand plans for years on end.
And meanwhile, despite endless pledges to abolish poverty for good, it gets worse. And worse.
