Subsidies are (or at least should be) intended to spur development by front-end funding of companies providing a valuable service or product, until they can be self-sustaining.
Every year, we grant subsidies to companies that have profits exceeding the subsidy for the same year. That means the subsidy is only contributing to their bottom line. Coupled with tax breaks allowing corporations to pay less than their fair share, taxpayers are paying for companies to exist without any taxpayer benefit.
Make subsidies returnable to the government once the recipient is profitable above the subsidy amount for the same period. It is only common sense. Then that subsidy money can go to other deserving companies once they have helped get one become profitable.
