You don't actually. Venezuela has vast amounts of wealth, which are distributed incredibly unevenly throughout the country. The pie could treble in size, but if 90% of the wealth is controlled by 10% of the population - poverty will remain endemic.
Well the only people you can blame in Venezuela for Hugo are the same people that ran the place for the last 200 years before he arrived. With all that oil wealth more should have been done, they have no one to blame except themselves. That being said I don't think setting up of a authoritarian police state is the solution to past problems. If you look in the region there are a few example of countries that appear to be solving their problems by improving governance, encouraging economic growth to raise people out of poverty. I don't see it as the old system or Hugo Chavez and nothing in between.
I'm afraid this is just as applicable to your own position.
If you read my response above you will see I'm not an either or kind of guy. I think people who see the choice in only two ways are really missing the boat on what could be.
