why most of the sites paying less for more work  

They pay us little and ask us to work more because they want to earn more from us and in less work.
Well i suggest you to join jillsclickcorner where you can complete there offer and can earn money. More over it's legit and i got paid from that site.
So now it's time to earn more work less.

That's the major problem. I am in freelancer.com. day by day i am amazed to see the status of work falling. People are getting paid $0.50 for 500 word articles. Just imagine!!!! I pity them who work for such meager income but they have no other choice. This in turn effects writers like us. Even the payperview sites like associated content gives return after much time. It takes too much time to build a portfolio of articles in these sites. Nevertheless, I am in love with this site...Wish there were more sites like mylot...

it's normal, everybody wants to do less and earn more, dont' you? so it's the same as the boss of the sites who want to earn as more as possible. and i don't come across a site that pay me more money and less work need to do.

Hi, I'm also a freelancer (odesk.com)and I have to agree that most buyers/employers offer lower rates for more work and it's mainly because providers/freelancers kept on taking jobs/rates like that, especially the newbies that needed the feedbacks. If no one will bid/apply on low-rate jobs then the providers will most likely increased their payment rates just to get the work done. :(

Hi! I'm just curious. What sites did you join? I currently do mostly online academic writing jobs but I have other links on my profile which I have actually tried and it has paid me for my work. You can follow me on my blog so you can have regular updates. Just to let you know, there's nothing in this for me. I just want to help fellow writers and friends here on myLot to be able to get good online employment.

Thanks and happy myLotting!

They demand more and pay less because they can get away with it. It's a free market economy, there are more people wanting freelancing jobs than there were before, ie supply of freelancers up, so price goes down. I have started writing fror Demand Studios @ $15 an article, if you are happy to write American English. Alternatively there are several sites that have an Adsense revenue share option for your articles

This may have something to do with the current economic situation. More people are looking for online work, while unemployeed. So more workers after the same job means they can increase the work load and decrease the pay. As the old saying goes desperate times call for desperate measures. And the thing is these freelance groups are taking full advantage of this.

You are 100% right that most sites pay the workers less than before. The reason is simple economic theory.

Demand for workers is less and the supply is immensely available. So the sites and the job providers exploit the workers.

Nothing can be done on this, it is inevitable.

probably because these sites overcome their lucky period and so they need more money to survive!!
In this way all workers must work more and be paid less so sites can earn more and they still go on

if sites dont do this what make this all sites to earn more money.so its the rules they also here for make money
