Tropico 4 is kind of the peak of the series. Later games streamline gameplay more. For example, you can no longer fine tune the wages, but rather have 3 or 4 money bags representing 3 or 4 tiers of wage distribution. On one hand, this is a marginal change in reality because wages were merely meant to draw scarce labor to different buildings, so they basically scaled it back to 4 levels of priority (which is probably plenty. The construction priority only has 3 tiers as well). On the other, it builds a general vibe that makes the games feel increasingly simplified. They're already relatively easy, so you start to feel like you're playing a phone game or something when they're made even simpler.
