There are more employers in most towns than just Amazon; everyone who works there thinks it's a better option for them than the other jobs available to them.

The workers are also free to become shareholders; Amazon is of course publicly traded.

When you’re done licking Bezo’s boots, go talk to those people you think are “free to become shareholders” (when they live paycheck to paycheck) or free to work elsewhere (when amazon or walmart have shut down the shops that used to be on Main St.).
