When a company start-up becomes successful, many many entrepreneurs look for an exit plan to realise their investment and the worth of the business. They could look at floating, or they could look at selling all or part of the business. I wouldn't, therefore, suggest it's a stranglehold on enterprise - perhaps the opposite, in fact: after selling growing businesses, many people then go on to start new ventures.
