Is it too easy to get rich in TS4?

It depends on what I choose to focus on in each household. Bigger households with kids and such I find it to be more difficult to make money because I'm focusing on multiple sims at once, so instead of focusing on one sim and their career, I'm focusing on five and their careers/school. Plus with bigger households means more money to spend, on expanding my house, to furnishing rooms and whatnot, so the money I make goes away pretty quickly. And as my house gets bigger in value my bills increase. I find it's a lot easier to make money once the house I'm currently working on is complete, because I'm not spending so much anymore. But it also depends on if I even want my sims to be rich. At this point of playing the game I know what can make my sims a lot of money, so if I want a sim of mine to get rich, I'll focus on game play aspects that can help with making money fast, however if I want my sims to live a more humble life with a little bit of struggle, I avoid those methods of making money.
