I have paid UK tax for fifty years, part of my tax money went to compensate slave owners for their loss of revenue.
In other words, they've been stealing from you to "pay" dead people who cannot receive your money.
These slave owners have been dead for a hundred years, but I have been paying dead people compensation until 2015.
You are guilty of what is called a "sunk cost fallacy."
It is "the phenomenon whereby a person is reluctant to abandon a strategy or course of action because they have invested heavily in it, even when it is clear that abandonment would be more beneficial."
You have invested the last fifty years of taxes to "compensate [dead] slave owners." Yet you are reluctant to abandon the idea of being taxed to pay dead people because it would mean the last fifty years of your life has been for nothing.
I can guarantee you, based on the reality that dead people can't be compensated, that the tax collectors aren't giving your tax money to dead people, either slave owner or slave, they are using it to line their pockets.
