The next question that pops into our minds is; how can these models/celebrities survive in this tough competition? Well, there are a few ways to keep models/celebrities competitive in the modeling/entertainment scene. Either these models/celebrities are born rich like Paris Hilton, or they have tons of savings in their bank account! For those models/celebrities who come from a normal family and wish to stay competitive in the entertainment industry, most of them will find a sugar daddy to pump in money for them.

As a model/celebrity, they may do a lot of PR work to publicized themselves and stay in the lime light, however, this PR work will not necessarily be remunerated. The return of this time invested on PR related work may or may not be visible in the near future and is not measured by money. The hope d return is measured in future fame (Something that is not easily measured).Money is what we need to pay our daily bills! Some models/celebrities might even throw parties and spend on entertaining on their potential clients. People might not know that those money is coming out from these models/celebrities own pocket to organize these lavish parties!
Models and celebrities might look glamorous from the outside look, however, their level of fame for money is unjustifiable! Unless they are consistently working in the lime light, these names have no substance! They are just vain repetitions.

Talents are needed to sustain and extend the shelf life of these models/celebrities fame. Either models/celebrities know how to play politics to stay on top of their games, or they have reserves and funds to back them up to keep up their fame in the entertainment industry. If these models/celebrities are not well-equipped with these two important attributes, then they can be eliminated at anytime! This is because they are not competitive enough in the tough entertainment business world.
(Mariah Carey)
Models/celebrities are going after scarce resources of media coverage and sponsorships. That is why to stay on top of these games, models/celebrities are expected to do a lot more and have enough reserves in the bank!
