There was a large desire for slaves because these slaves didn't need to be paid, as long as they were fed, they would be able to work for any amount of time for next to no cost at all.
Slaves did not experience things politically, socially or economically because they were slaves, who couldn't vote, leave their owners or have a real job.
Hope this helps!
The American army proved unable to hold up against the British. The battle ended in disaster for the Americans. Washington led his troops and tried to defend Manhattan and Long Island against British troops led by General Howe. The British blunted the American drive and retreated to New York.
