Most man in Poland? I cant find any statistics and i know that Poland was one of the more industrialized parts of Russia but i think that Poland around this time was still more of an agricultural country. I know that a big part of the people living from agriculture are the landless agricultural workers but they too shoudnt be in that bad of a position. What i mean is that a lot of people are in the armies so there is a shortage of working hands meaning that those who are still there can make a pretty good deal for themselfs. I think the bigger rift should be between the rural and urban Poland cause those who really suffer will be those in the cities.
The urban/rural divide is very strong, but keep in mind Poland is also divided between the land the Russians despoiled and the part they did not, and the population has been brutally uprooted by war. There are now hundreds of thousands more people living in cities and towns that before the war. Huge numbers of refugees were driven from the eastern parts by the advancing Russians and ended up in the salient the NA was able to defend, or in Germany proper. This pool of floating labour depends on some form of employment. A lot of them will never be able to return to their original homes, their houses destroyed and the rural communities torn apart. All of them at some point or other faced the choice of having to give up some prized possession for a paltry amount of food, or go hungry. Many are recruited for the labour brigades or go to Germany as agricultural labourers, competing for wages with Russian POWs. There is a lot of resentment of those whose communities and land holdings are still intact here. They feel that they gave all while the fat cat landowners gave nothing.
Doesn't Poland still have a currency crisis? I would expect urban Poland has access to a small amount of money but little other than what food is brought in not going to the army, while rural Poland (the part not near the army or their supply lines) has food but difficult access to any money.
The situation is even worse than just a currency crisis. It's a humanitarian disaster in the middle of a war. Basically, you have a government with no real institutional grip trying to acquire the resources to fight its war and feed its population while having neither a working currency nor a tax base. Meanwhile, the Germans, who have these things, are being unhelpful at best.
The established urban population is squeezed, with many young men away at war (recruitment for the NA was always more urban than rural). Industrial workers supplying the war get rations on top of their pay (which is often given in barter goods or IOUs), so they get along most days. But with masses of refugfees cramoped into the cities, many of them rural and desperate, competition for labour is fierce and prices sky-high. Many depend on charity funelled mostly through religious communities to survive. Meanwhile, the Army Council is organising work gangs you can be drafted into if you're an able-bodied man or unattached woman with no proof of employment. Given conditions in those gangs, employers have enormous power over their staff. The threat of dismissal is often enough. Of course most urban employers are also squeezed. Either they go into the black market or produce for the war, otherwise their business is dead (and war production is mainly paid in paper zlotys, so you really need either a class I contract that gets paid in mark or black market contacts to survive).
In the countryside, you have a similarly stark divide. Owners of large farms or estates were often left unmolested by the Russians even in conquered areas (because they dealt with officers instead of troops, and on the assumption these people might be needed to run the country post-war), while smallholders were burned out, massacred, or fled. Landless labourers and newly homeless ex-tenants are at a great disadvantage. Some gentlemen farmers are parlaying their position as employers into near-feudal powers. Tenancies are unfilled or auctioned to the highest bidder. Smallholders must sell or mortgage their land to eat, or lose it to neighbours while they are stuck in refugee camps. A consolidation was due, and landlords use the war to accomplish it. Some people gain, but it's down to luck and unscrupulousness, and most lose out.
And of course the corner that the Russian army did not reach - the salient that the NA defended at Skiernewicze and along the Vistula - still has functioning rural communities with crops in the field and cattle in the stables. These people are making money hand over fist selling to the urban centres and refugee camps - at least those that own the land, not the labourers whose wages are depressed by competing with refugees and who - as 'autarkic rurals' - do not get ration cards.
It is hard to overstate just how sucky life is east of Germany right now.
