Actually, that is not strictly true. Many hidden costs for things like cleaning polluted water are paid for by the government, but the government’s bills are paid by us - the taxpayers. Of course, some environmental damage is not fixed or paid for, but we know that such damage will be felt in the near future. For example, when polluted soil is not cleaned, it will start to cause health problems — with associated costs. Then it will be our children or grandchildren who pay.
