MRF, I thought the same thing when I first started playing the game, however it doesn't take long before they can afford these things. The fruits and candies are costly but are the best way to praise your peeps for working on their careers...After a couples of pats on the back with the praising glove and then a couple of candies your peeps will become addicted to work.

Also some of the most lowest paying jobs end up making the most in the end...You'd really be surprised. Hope this info helps you!
