What you just said is truth. You talk about how big corporations are taking advantage of these loopholes to avoid paying their fair share. And this is so painful to see our ordinary citizens and the ones that are carrying the burden through high taxes and at the end benefiting less from it all.
The system was built for balance but now it's completely tied to people and towards corporate greed. This is a big problem.
There has to be a change which is to demand accountability and transparency. If people must pay taxes locally, companies operating here should too. At least it will bring fairness to the system. And this fairness should not depend on wealth or influence.
