Don't know about the universe you describe, but in ours what people "pay" is the money they give, not the money the company receives, so not, the Yankees don't "pay" more.
Okay fair point - replace 'pay' with 'contribute to Paradox's sales' and it is accurate.
And, for the record, I understand what you're saying but you are using all the wrong words to describe it (not to mention that where I live, the government only provides for social groups I don't belong to - parents, disabled and unemployed - so "I" specifically pay "a lot" more).
You also have to think have you
never been of will you
never be in one of those groups you mentioned - because asking you to contribute then when you are unlikely to have the funds is more problematic than asking you now when you do.
Also you have almost certainly benefited from a large amount of government spending - probably to the tune of around €60,000 when the state provided for your education - with a probable €40,000 in healthcare whilst you were a young child as well, a large proportion of that being costs associated with your birth and vaccinations.
This is a classic example of the free-rider principle, people who are fully employed and in good health do usually complain about taxes they pay but once they suffer unemployment or ill-health then they realise the benefit of a system which spreads the risk compulsory over all individuals.
20 is too much, many won't be able to afford it. Better to make it 15 and sell more.
My advice to you would be never go into business - businesses are there to make a
profit not to just make
sales.
A business that chases sales instead of profits is a business that will fail.
