This is crazy how economy is tilted in favour of these big corporations. If you are a worker, it is not uncommon to pay over 40% of tax and if you work on your own small business you can pay even more and have very little left to reinvest. Then you have progressive tax that is preventing you from saving much - if you want to save for a deposit to buy a house, spend time on education and getting a better job, you'll g…
First: "if you work on your own small business you can pay even more" ... huh? If you own a small business, you're getting the corporate tax rate, and chances are you're not paying much of taxes anyway because your net revenues probably are $0 or close to $0. What are you talking about here?
Anyway, it's weird to state it as corporation vs worker with respect to tax rate. Those are different kinds of things. Every worker in a corporation pays personal income tax. Shareholders also pay taxes on capital gains and dividends. A corporations also pay plethora of other taxes (like payroll taxes). So let's not pretend there is no tax benefit to having corporations do business in your nation. The vast majority of corporations also have a profit margin in the range of 5%-10% - so it's not like you see crazy profits all over the place.
And given the nature of a corporation and the role it plays, increasing taxes (to say, the level of personal income taxes) to fulfil the fantasies of anti-capitalists, will have disastrous effects on the wider economy of a nation because increasing cost of doing business will be passed down to consumers and workers and possibly lead to large-scale dissolution or abandonment of your region. The vaunted nordic countries opted for a model where personal income is taxed very high, but corporate income is taxed competitively (until the Trump tax cuts, Nordic corporate tax rates were universally lower than those of US).
Finally, tax policy is an area replete with potential 'unintended consequences'. Most people (myself included and you as well - after reading your comment) don't really understand why everything is the way it is (and there are good reasons for many tax regulations), so I would be careful with advocating for restructuring the entire system - you're going to screw it up worse than you think it is now.
