Could anyone correct this paragraph please?

Japan's work force needs to be retrained reconsidered for more increased effectiveness. However, I am a bit worried that if Japan tones down the intensity of its work force training, the quality of work that they do have kept will get lower decrease. The quality and fineness excellence of everything that they do is part of what something that Japan can be proud of. Hopefully, companies can increase the labour force, then decentralise each person's roles, so that they can have more time off offs. However, since the population is decreasing, and such, so it's this is another issue that needs to be addressed  to be discussed.

Thank you very much in advance. You're welcome!  :)
