The current government is doing very bad things to their citizens and anything of value given to the current government will be turned into resources that will help the current government stay in control (and continue starving, arresting without cause, and murdering their citizens).
Citizens are free to criticize those in power in the US without consequence from the government, while those in power in Venezuela will see those who criticize (who have influence) arrested on bogus charges, or otherwise are subjected to violence from the government.
