Private business for government profit
When the government describes private businesses as "partners", we
have to suspect they have converted it into a partner for their
profit. That is corruption.
The last example, that of private space stations, might not be so bad.
If the three companies operate space stations at their own expense, and
make a profit, that's not corruption. However, if the government subsidizes them all to "compete", we won't get the benefits of private competition, so we
may as well pay publicly for a space station owned and run by the country.
