Yeah. So maybe a country should at least try.
But apparently, because no country has ever tried UBI, no country ever should, regardless of how much economic theory or empirical evidence suggests it makes economic sense.
You're a true conservative Argus. You really have a strong desire to irrationally conserve the status quo / tradition (which is the definition of conservatism) even if it makes no sense what so ever if you accept arguments like 'X has never been tried before, therefore we should never ever try X'.
It doesn't need to be necessary to justify it. Actually, you don't even need to believe that decreasing CO2 emissions is beneficial for Canada to justify taxation of CO2 emissions. CO2 emission taxation can be justified on the grounds that, up to a certain point, it is a more efficient form of charity to other countries than either aid or military expenditure, so if we were to implement CO2 emission taxation and cut aid/military spending, then we could do more charity for the same economic cost.
New Zealand and Netherlands appear to be in good shape.
But you want the system that gave us Trudeau, Notley, Wynne, Trump, Harper, Hitler, etc. Cause it's worked out so well!!
Let's be honest. We both know that the main reason why you oppose changing FPTP is because it favours Harperites such as yourself and the extreme identitarians of the fake liberal party run by Trudeau. It allows your minority view point to occasionally hold all the power and denies various groups representation (classical liberals, libertarians, communists and other groups get zero representation). You are inherently against the idea of a representative democracy and are only interesting in how frequently you minority beliefs can hold power.
