But what is a minimum standard of living? That is really subjective and goes to the heart of your argument. For me, a minimum standard of living is a house, food, energy, water, education, healthcare, social care, defence/safety, street lights, transport, welfare, ability to live beyond "a basic standard" by way of a guaranteed minimum income...there are probably other examples...
I think the state should provide or enable each of these things from the common good of taxation. I believe most people would pay more.tax if they believed that they would reap the benefits but we have been conditioned to believe that taxation is bad, state spending is bad and that if we let people fend for themselves they will all be fine - despite the fact that this is manifestly and demonstrably untrue.
Austerity kills. The lack of social housing has created profits for private landlords, prices people out of housing and increased homelessness. State Education is increasingly benefiting shareholders. Healthcare is increasingly benefiting private companies. Utilities have made a few rich while the rest have paid the bills.
If the state only looks after those that cant help themselves, everyone else is left to fight for the miniscule scraps that the minority allow us to have.
I am a socialist. I believe that the state should be the means by which the majority benefit from the success of our collective effort and not the minority. If the state only looks after those who cant help themselves, the state has no meaningful contribution other than to mitigate the impact of capitalism. If something needs mitigating to that extent, it shouldn't exist.
