Avoiding tax is legal, encouraged by the state and everyone does it.
Er, it’s legal becuse the people with power to change the law are the one’s benefiting from it the most.
In other countries it’s legal to rape your wife, does that make it right?
Laws and ethics and right from wrong are very grey areas..
It’s unethical…so no, people are not being thick. I suggest you are being naive if you think simply because it’s legal makes it right..
