All the Simoleons, LP, and SP too EXPENSIVE NOW

Why are all these Green Simoleons, Yellow LP, and Purple SP points are too expensive now, when we move up too the next level plus when the Sims salaries are very low? Don’t sounds fair period it just to make us to spend more money when its not enough so I believe Ive stop at level 28 n VIP at 11, because the game has gotten harder to upgrade or buy anything new items, they want close to 3,000,000 Simoleons to upgrade just a small house in Sis Springs Tall tree house…..attachment below….and when I purchase on of their deals assuming it’s free too use but nope this what they do cost me high Simoleons to get the items in what i paid for not cool n not fair……i need to cancel my sims account they’re not so promising I spent too much money
