That middleman job can be much riskier than people imagine. Companies that doesn't want to deal with gov can do the job, sometimes at a lower cost than the bee companies purely due to the middleman in this case.
If she got the tenders honestly and without corruption why hold it against her? The gov contractor runs the risk of providing the service via a sub contractor, pay that sub contractor and them gov doesn't pay, or don't pay until months after. I know of quite a few companies that have gone bankrupt due to this.
If I were to take that risk and make a killing I'd have no issue in enjoying that money. The same people being sour now would enjoy your downfall if you lose everything due to gov not paying you. If I were to even have my own company I'd not do business with gov purely due to that risk.
