Sad to read this. Most LatAm leftist governments tried the same formula over the past 2 decades, with disastrous consequences. Focusing public borrowing on the domestic market means that the government will compete with households and businesses for capital, which have a much harder time raising capital internationally.
This will make it much harder (and raise interests) for households and businesses to secure capital for new investments (especially when the domestic savings rate is so low), restricting supply growth and possibly leading either to inflation or to an increase in imports.
That, coupled with a low or nill savings rate, an over-reliance on government for retirements and a low retirement age, means an economic disaster, exactly like the one in Argentina and Brazil.
