Quite a lot, but keep in mind that Franco was not a communist dictatorship, Franco was a traditionalist right-wing regime, there was much more economic freedom than now and much more prosperity.

Under Franco Spain was the 8th world power, now we are barely in the top 20.

With Franco there were hardly any taxes paid, to finance himself he used a mixed model of state companies, for example car or truck factories, if you bought a car or truck of that brand it was financed to the regime.

Franco built practically all the current highways, including the model of private highways, all the dams, and 8 of the 10 nuclear power plants that Spain has had.

In conclusion, Democracy has been the ruin of Spain, contrary to what happened in the communist regimes. 

 Forgive me. I wasn't trying to compare Franco to communist regimes but rath3r just pointing out semi-recent governments that people are still nostalgic for!
