Once it is gone in about 2 billion years, plus all these poor people out there you keep giving money too get use to that lifestyle and guess what next, more tax and less people doing the work, inflation goes higher again.
The tax will only compound the problem. At the moment investors and mine owners continue to build businesses and employ people. The taxes stolen are taken and used by the government to build liabilities. Who is paying for the maintenance, upkeep, taxes, rents on social housing not the people in them because drum roll, they don't work or invest or build businesses.
So instead of having a fingereddwarves you have fingered country.
