Import taxes like that only make sense if national industry is built up first. Forcing autarky without establishing the proper groundwork for an independent economy is stupid. In any case non-industrial purchases really have no reason to be taxed excessively no matter what because if national industry was productive enough its prices would be lower than foreign prices anyways.
Foreign investment income should be taxed more than domestic investment income to encourage domestic investment. That said, this policy is only good if enforced. Moreover anyone who isn't financially independent shouldn't have to pay any taxes in my opinion. I firmly believe that only corporations, the financially independent (rich) and people who own more than a single home should have to pay any taxes at all.

It doesn't surprise me that this government isn't enforcing any protections against deforestation but the last one didn't either. An actual socialist country would be enforcing these protections so I don't see how it's a knock against socialism that the amazon is being deforested. It more just shows that the Brazilian political system doesn't work more than anything. I don't think it's an accident that Cuba is the most sustainably developed country on Earth.
Also the Worker's Party and current Government coalition in Brazil isn't a socialist coalition. It's a social democratic coalition (nomatter the name) and it should come at no suprise that social democracy isn't working in a middle income country with a corrupt political system and highly developed market economy. Social democracy doesn't actually change the economic system or impeded capitalist markets. It is those very capitalist markets that are profiting from the destruction of the Amazon among other things in Brazil.
