We can't blame the government. The major focus of any country is to generate money from its people. How is this possible, levy tax over the people. Atleast Argentinian government is making plans for the taxation. However this can't be made immediately, so the focus is good with short term changes. Already India have put 30% tax which is very big and limit people from using it.
Indeed we cannot blame the government for such actions since every citizen has the obligation to contribute towards its country and this is done by taxing us. Taxes is what fuels the country to run and improve. Although some countries do not see much improvement due to corruption, it still does help a bit. But main point is that as a citizen of our country we must not avoid our responsibility towards our country. And for the country, it would be best if the taxes imposed aren't too unreasonable as the 30% tax in India as what you have mentioned. This is just crossing the line.
