Capitalism without social control is like a football match without a referee, only playing for your life. The strongest are free to break the rules and take everything. Then they make their own rules, so they can keep it all.
Right wing arguments make much of the idea that everyone should be free to own their own property and live how they want to, without government interference. And so they should. Until they dump sewage into the rivers and onto beaches out of laziness or incompetence, or raise the price life-saving drugs so people who need them are denied their use. Then someone has to step in and prevent it. Someone has to make the greedy and selfish behave better and ensure a fair game.
Right wing arguments make much of the idea that markets will regulate behaviour. If the price is too high then nobody buys it so the price comes down. If a firm behaves badly people will boycott it and punch their profits. For small or medium size firms that sometimes works. But the larger the company becomes, the more it can bend the market and be free of control. They will have a monopoly and no competition, or reduce wages to starvation levels by ignoring the rules or exploiting the desperate. If they don’t get their own way, they try to influence governments and threaten to take their jobs to another country. For example, Dyson cleaners, owned by someone who worked hard to take the UK out of Europe, are now made in Malaysia instead of Wiltshire. So Dyson gets richer, pays less tax into our country, and the UK workers get nothing. But UK citizens still buy Dyson cleaners. Influence only seems to work one way, in favour of the powerful. Markets need to be moderated.
Socialism is not about wanting to control people unnecessarily. It is about moderating the selfish and lazy, the powerful and manipulative. It is not about taking away from the rich, but preventing them from taking too much away from everyone else by breaking the rules then making up their own.
Nobody likes the referee when their goal is denied. But nobody can be truly free unless we acknowledge the need to a have one, and to play fair. Uncontrolled capitalism gave us slavery. It still does in many countries, including the UK. All we ask is that the greedy and selfish stop pretending to be somehow morally superior, and the rest of the country wakes up to the lies they are being told.
