No it doesn't. And you citing a government debt stat doesn't prove it. As a counter-example, the UK set up the NHS in 1948 when their public debt was over 200% of GDP.
You are ignoring the fact that NHS started compromised to allow the payment of UK's debt. And consider that Brazil's interest rates are already high.
So you're saying it's possible?
No, I'm saying UK already had to compromise, and Brazil doesn't have the same economic advantages as the UK did. In all, while I haven't stated it's 100% impossible, I haven't stated it's possible, even less so preferable.
