I think that every tax on what is harmful should always be increased to discourage people from consuming that product or service.
Some examples of what I am saying are... cigarettes, alcoholic beverages, hookers and also gambling.
I see, I'm starting a controversial discussion, but given the need for greater tax collection, it's preferable to raise the rates of non-essential and harmful services to the population (whether in terms of health or finance) than for other essential services.
Of course, every tax increase is bad and it needs to be done reasonably when it's unavoidable.
I think every business that is destined to make people's lives worse should be taxed very very heavily. However at what point are you doing something that is against freedom? For example beer is bad for you, it is not healthy and if you drink too much beer for too long you will die, that is a known fact but its legal and you can buy it and drink it if you want, for a world where many drugs are bad for you and illegal, for some reason things like beer and cigarettes are allowed.
So if you say 500%+ tax on the price and 50% tax on the income for something like beer, so instead of 3 bucks its 15 bucks per beer, would that be against freedom? I think many people will say so, but then how can you allow weed to be illegal in many nations? Long story short there is a line there but it is a blury line and nobody really knows what to do about these things.
