Yes, and raise taxes on all income brackets

It would discourage people from living in the UK as it would require the funds that we can choose to spend on ourselves be moved into a less efficient and more abused system.

if you have earned the money then why should you be taxed more then people who havnt work as much for it

No, governments should not raise taxes on the rich because they should not have to get charged more money just because they earn more money, this is mostly due to the fact that wealthier people do longer hours at jobs which require a minimum skill set or degree to do.

Tax is already high and clearly not being used efficiently with inflation, raising taxes will only do more harm to working class people

Raising taxes in any capacity reduces the freedom of citizens. It is saying that the state does not trust you with the money you have earned through hard work. Government projects are hopelessly costly and inefficient, take HS2. Raising taxes and raising public spending is taking something of value, and returning something of less value. Citizens should be allowed to choose how to spend their money, and not have half of it given back to them in government grants. Financial control is the first step to totalitarianism,.
