That's strange, because the union is saying exactly the opposite: it's questioning the fact that it is legal to get so much money. The union's press release is very clear; it seems to know what it's talking about. Yet it's saying the opposite of what you're saying. According to the union, the amount of $1.9 billion is higher than what should normally be collected by the government.
Are you saying that the union doesn't know what it's talking about?
