There is risk in any action taken due to the fundamental lack of information regarding events occurring in the future. I agree with you that much of it is luck, this at the same time does not mean because one is born lucky that they now need to suffer to bring someone else to their level. I disagree that it is meaningless, I believe that since no one person is entitled to anything from anyone else (to think otherwise would be to support slavery), the only morally correct form of interaction is through consensual voluntary action.

I do not think we need checks and balances. Minimum wage actually harms those who are most disadvantaged - if I am hiring two people and I must pay them the same amount, there's no reason I would take the socially less valuable person. At the very least, eliminating the floor would allow the disadvantaged to compete and make racists pay for their prejudice, i.e. "Do I really want to pay $10.00 for a white straight privileged [whatever insert here] or $5.00 for a black trans [etc]".

Inheritance tax is violence against those who pass on their wealth. If you have indeed earned so much that you would like to ensure your lineage, what right does anyone else have to stop you? Why is it wrong for you pass on wealth to your children? Whose business is it? What if instead, you simply lived a thousand years and kept your wealth?

If you want to donate money because you are very rich and have a lot of money to spare and truly believe this, then by all means, you can even pay more in taxes nowadays and never file a return. Nobody will stop you.
