A minimum amount should be calculated as “cost to raise a child”. The non-resident parent should be expected to cover their proportion of this. If they are unable to, the government pays it, and it accumulates as a loan which affects credit ratings more heavily than other loans - for example, credit cards, mortgages and car finance would be refused. Only those with a disability that prevents them from working would be exempt from repaying the loan.
Companies should be prevented from paying wages where the highest wage is more than a set multiple of the lowest wage. The highest salary can’t be increased beyond that hourly rate multiplied by full time hours (e.g 40 hours per week). The multiple could be higher for small companies, reduced for medium and again for large companies, to help owner managed businesses get started.
Dividends should be banned for medium and large companies any of their staff are paid below a set living wage (an actual living wage, not minimum wage which was renamed).
Once the right people are fairly paying their share, the government can look at stepping in to provide support where it’s needed, instead of taking on the role of absent fathers or companies who pay the CEO or shareholders before their staff
