Ok, cite an example where the conditions are just about starving, rather than being forced to work under the lash or at gunpoint.

    The majority of the Chinese immigrants were male, many having left wives, mothers, sisters, daughters, and future spouses at home in China. Foreign miner taxes in California, often aimed squarely at Chinese immigrants, prevented them from staking mining claims, which in turn forced them to look for opportunities elsewhere.

    The CPRR hired an initial group of 50 Chinese workers that in short time dispelled the negative assumptions held by some CPRR managers. They fostered a reputation of strength, efficiency, and reliability. More Chinese workers would be hired and they held a variety of jobs: laborers, foremen, contractors, masons, carpenters, cooks, teamsters, interpreters, and medical professionals. Even so, racial inequalities persisted. Chinese workers were paid an average of 30% less than their white counterparts. They were segregated in work camps and had to pay for their own lodging, food, supplies, and equipment.

    The disparity came to a head on June 24th, 1867, when all Chinese railroad workers from Cisco to Truckee, California, a 30 miles section of track, stopped work.

Confrontation, Threats -- and a Bloodless Resolution

    After a week's worth of lean rations had settled upon the men, Charles Crocker returned to the work camps. He dictated the options as he saw them: wages and hours were immutable. If the hungry Chinese workers returned to work immediately they would only be fined, but if they continued on strike they would not get paid for the whole month of June.

    Motivated by malnutrition, most men agreed to return to work

Numerous other examples in colonial history.

Yes you can, by coercing them in various legal and illegal ways. Your original comment was just the one quoted sentence above. It is not correct.
