The devil's advocate argument about transport could be taken further.
Why should anyone get anything that they haven't worked to pay for themselves?
Obviously in the current economy it's because wages do not cover basic living costs for a vast number of people. A significant number of them have physical and mental disabilities that prevent them from working be it part time or full time. The argument that families and communities should support them is often trotted out, but those capable of "caring" also have to live and a dual household income is the gold standard now.
The government has a covenant with the people who vote it in. Part of that covenant has evolved into the provision of a safety net for people, often temporarily but sometimes permanently, paid for (allegedly) by taking taxes to support both general infrastructure (bins, policing, health services etc etc) and the safety net. Because it recognises we do not live in a free market capitalism economy and the markets fluctuate.
These days catching votes by demonising one tiny part of "spending" and vowing to give voters what the majority demand in the moment regardless whether it will help or harm the collective is the norm and technology and media has advanced in such a sophisticated manner the populous can be lead by the nose via algorithm in the desired directions. Data is one if the most valuable commodities in the world for business and politics which are now incestuously intertwined.
We are seeing rapid global destabilisation at a rate that previous provisions cannot keep up with, as far as I can see, due to many factors not least being the capitalisation on the instability which benefits a few and leaves countless as collateral damage.
Everything is out of whack and I can't see a good end to that.
