Sad reality is that Tax holidays will always exist for the rich and powerful, and even if they didn't they will always find ways to beat them and defend themselves on grounds of providing jobs to many other people.
Otherwise a progressive tax system is the way to go so that the Rich aren't richer and vice versa and simply ensures the Rich contribute a huge chunck from their income and other bracket contributes a smaller portion of their income.
There are still rich people who actually pay their taxes and their tax are higher than lower earners, yes I also acknowledge that their are rich people who find away to evade tax some actually do it legally too but hating on the rich is not the smart way to go.
The government may support some rich people to get richer but there are also some rich people who get their wealth the right way too.
But in general I think the tax situation of many developed countries is actually ripping of their citizens and it would be very helpful if that can get addressed.
