No, no you arent. Money given without strings attached is just that. Claiming ownership of another humans labor is called slavery.
It might be evidence that you or your government isn't benefiting you with its spending. That doesnt put obligation on the recipient.
Does the same reasoning apply to student loans? Is the lender engaging in slavery by claiming entitlement to a portion of the student’s future labor?
My taxes aren't "money given without strings attached". They are payment for services that benefit myself and others in the community. They're not a free gift for the government to hand out, that's theft.
