People smarter than you are answering. You’re just choosing to dismiss It. Like I said, it’s pointless.
You've pointed to links to books that I can't read and you likely haven't read, and tweets that show no evidence whatsoever. There's lots of books, PhD academics, and tweets that are critical of MMT.
If someone has made calculations on longterm projections of the cost/benefits of debt borrowing and can show the math I'd like to see it. If the math of endless borrowing shows a net economic gain for Canada i'll be all for it no matter the theory.
What you've done is decided you like the Liberal Party best and filled your twitter feed with endless tweets of people who support them or their policies to confirm your ideological and partisan biases. That's not evidence. If you or Freeland want to put Canada on a very different financial path then show Canadians the math with projections. The formula and calculations shouldn't take up more than a page or 2.
