Im fairly new to SwiftUI and Im trying to build a small game to get used to the syntax but I have the problem that I created a class and created 3 instances in the @main struct but when I try to use them in my View they all turn into the first instance

Class:

import Foundation

class WorkSpace: ObservableObject {
    var title: String
    var income: Int
    
    init(title: String, income: Int) {
        self.title = title
        self.income = income
    }
}

@Main struct:

import SwiftUI

@main
struct LifeSimulationApp: App {
    @StateObject var doctor = WorkSpace(title: "Doctor", income: 60000)
    @StateObject var lawyer = WorkSpace(title: "Lawyer", income: 50000)
    @StateObject var carseller = WorkSpace(title: "Car Seller", income: 30000)
    @StateObject var player = MainPlayer()

    var body: some Scene {
        WindowGroup {
            ContentView()
                .environmentObject(doctor)
                .environmentObject(lawyer)
                .environmentObject(carseller)
                .environmentObject(player)
        }
    }

}

View:

import SwiftUI

struct OccupationView: View {
    @EnvironmentObject var doctor: WorkSpace
    @EnvironmentObject var lawyer: WorkSpace
    @EnvironmentObject var carseller: WorkSpace
    @EnvironmentObject var player: MainPlayer

    var body: some View {
        NavigationView {
            Form {
                HStack {
                    Image(systemName: "text.book.closed.fill")
                        .resizable()
                        .frame(width: 50, height: 50)
                        .foregroundColor(.blue)
                        .padding()

                    Spacer()

                    Text(player.occupation)
                        .font(.title)
                        .padding()

                    Spacer()
                }

                Section {
                    Toggle("(doctor.title) ((doctor.income)€)", isOn: $player.isDoctorOn)

                    Toggle("(lawyer.title) ((lawyer.income)€)", isOn: $player.isLawyerOn)

                    Toggle("(carseller.title) ((carseller.income)€)", isOn: $player.isCarsellerOn)
                }
            }
            .navigationTitle(player.name)
        }
    }
}

struct OccupationView_Previews: PreviewProvider {
    static var previews: some View {
        OccupationView()
            .environmentObject(MainPlayer())
            .environmentObject(WorkSpace(title: "Doctor", income: 60000))
            .environmentObject(WorkSpace(title: "Lawyer", income: 50000))
            .environmentObject(WorkSpace(title: "Car Seller", income: 30000))
    }
}
