When common land was divided up into enclosures the immediate losers were those users of the land with no legal rights and thus no claim of compensation in the form of their own enclosure. They became landless and would thus seek to be employed by working the land for wealthier landowners.
It was also often the case that those with land rights who did receive compensatory smallholdings encountered a threefold disability:
1. the amount of land they were allocated was so small, though in strict legal proportion to the amount of their claim, that it was of little use;
2. the considerable legal, surveying, hedging and fencing costs of enclosure were disproportionate for smaller holdings;
3. under the Poor Laws, the taxes of the small landowner who worked his own land went to subsidize the labour costs of the large farmers who employed the landless at poverty level wages;
which may have necessitated the disposal of a white elephant smallholding to the wealthier landowner.
'A Short History of Enclosure in Britain' covers this and more quite well...
