(5) Economic condition demand not only to

Economic condition demand not only to rise wages and salaries but also to reduce syndicate induced price level.

Is the above sentence correct/makes sense?

My suggestion:

Economic conditionS demand not only A rise IN wages and salaries but also A REDUCTION IN syndicate induced price levelS.

Economic condition demand that we not only rise wages and salaries but also reduce syndicate induced price level.

what about now? Is this correct now?

No. You need the plural of ‘condition’ and you also need the verb ‘raise’ when you have an object (wages). ‘Rise’ doesn’t take an object.
