Despite the sizeable amount of support Batista received from some factions of the Cuban population initially, there were groups that were single-mindedly devoted to removing Batista from power. Student groups in Cuba actively rioted and protested Batista's position. The rebels attempted to undermine government authority and demonstrate that the administration was incompetent. They exploded bombs, derailed trains, cut power lines, and kidnapped or killed their political enemies . These acts served only to infuriate Batista, and he responded by killing rebel and anti-Batista supporters, and beating student rioters to make an example of them for any future dissenters . Batista promised plans that would bring Cuba out of the economic slump it was experiencing due to the troubles the sugar industry was having. Sugar was one of Cuba's main exports, meaning that a drop in prices severely affected all portions of Cuba's economy. Batista offered incentives for businesses to invest in Cuba. He publicized that the government would match, dollar for dollar, any hotel investment over one million dollars. This allowed for gambling establishments to inhabit Cuba, which eventually contributed to the moral degradation of the regime . While this investment policy was apparently supposed to increase the tourism industry, and create new jobs it also generated resentment among the Cuban people. Many Cubans were denied access to new facilities, and the average Cuban did not profit from the presence of new investors. Instead, Batista himself profited as he received bribes from the establishments and potential investors. Although at first, the feelings within Cuba were not as remarkably anti-Batista, as they later would become, a series of actions by Batista aroused the dislike of many Cubans. Despite his assurances that he was doing things for the benefit of Cuban citizens, he began his administration by eliminating opposing political parties, and suspending constitutional entitlements, such as the right to vote .
