The actual price of Poké Balls is ridiculous (the price in the games is a discounted price exclusively for kids). The services at the Poké Center are expensive, and services like daycare are for the wealthy. Even a bag of Pokémon food costs the equivalent of a third of your salary. That's why most adults in Pokémon only have one or two Pokémon.
Also, how do you expect to get a good job if you've dedicated 24/7 of your life to battles and failed to enter the world rankings? If you're smart, you'll divide your time between battles and learning a trade, job, or professional career. You'll never be a champion, but you'll have a second source of income, like most Gym Leaders.
Otherwise, prepare for a life of minimum wage or being a failed bum like Ash's father.
