Assuming this is a serious question: You/Your group needs some serious help.
What you do about it depends on your role/level of influence in your organization. Regardless of your level, I highly recommend reading Speed of Trust (like I recommended above). However, two example roles:
If you are the CEO/key leader, there is no excuse for creating/fostering this mess. You have to address the culture you have fostered heads on. Your complaint: “But it will cost too much!”. If that is your mentality, you are missing the point. Don’t look at absolute costs, look at value, that is what good CEOs do. If you can realize $2 for $1 cost, or $5 for $2 of cost, which should you choose?
The $2 for $1 is what you realize by creating/fostering a low trust environment. When you hire folks, find the best people you can, and then enable them. If you aren’t getting good people, it is either because a) they think your environment is toxic or b) you aren’t offering “enough” to compensate them. Note: compensation is NOT just dollars. It could be flexibility, it could be the ability to work on their side projects, it can be ability to learn new skills, or can be shared vision. Take your pick. In general, after some number of x $$$, money becomes secondary. Foster a culture of trust, mutual respect, and you will get dividends.
If you are at the “lower” on the totem pole, the answer is more simple. Ask yourself: can this org be saved? If you brought this up to leadership, would they work to change the culture? If not, then it is time to pack your bags/look for a better org. If they will listen, You have to decide if you WANT to save the org. If so, you have a long road ahead, but if you can pull it off, you will gain lots of experience and will rapidly increase your marketability.
Edit:
In case it wasn’t made clear, let me make this final point for the ceo/leader: Spend the money/create the perks that allow you to attract the people you can trust, then once you get them, TRUST them. Yes, verify, but if you don’t do this, you are doomed to fail. Also, either find a way to trust the people you have, or get rid of them. It is a disservice to both you and them to keep around people you can’t trust.
One big caveat: make sure you are someone THEY can trust too.
