Why does a 20% tax rate surprise you? It has almost become to standard across most of the world. Historically in the last fifty years corporate tax rates have been as high as 50% in the UK and US, even in the last ten years the corporate tax rate in America has been around the 35% mark. The main beneficiaries of lower tax rates are the super rich and it can actually be detrimental to the average person on the street the lower they get. Maybe the tax rate should be constructed around "rent-seeking" and value-producing" classifications instead - certain things like manufacturing products can be very helpful to the GDP of a country but other things like "sin stocks" such as tobacco can be detrimental and it might be better to charge them more. Do not be fooled by the media, owned by the mega rich, who are able to put out stories that a low tax rate is bad - they are the biggest winners and the wider society loses the ability to fund critical services from those taxes.
