We have a capitalist system anniebach. In fact capitalism is the most widespread and powerful political system in the world.
It was a brand of socialism, operating under a capitalist system, that brought in the old age pensions, minimum wage, new schools and hospitals, the NHS, tax credits, anti-discrimination laws, etc, etc. It is the Conservative Party, which most closely represents the "unacceptable face of capitalism" (ironically, Ted Heath's quote), that has opposed nearly all, if not all, these measures.
It is the uber capitalist's core reliance on the efficacy of a "supply and demand", "every man for himself", low tax economy that has brought us the degradation of almost every vital service in this country and a great many social ills.
