If there weren't any of those numerous unscrupulous "businessmen" and businesses intent on scamming, poisoning, bilking, short changing, fraudulently preying upon and generally exploiting the public's trust and gullibility to make a profit at the expense of the public's health and welfare, then we wouldn't need any laws and regulations to keep these crooks at bay, would we?
"Buyer Beware" is a poor excuse for allowing crooks, from those ultra-rich banksters and corporate robber barons to those hawkers selling knock-offs from their car trunks an easier time to do what they do by killing those very laws and reg's that prevent them from committing the crimes those laws and reg's were created in response to the threats these crooks represent.
Just look at what happened during the Bush/Cheney years when Bush and Cheney turned a blind eye to all of the violations their business buddies perpetrated against the public. In comparison to what actual damage took place and the very few who got convicted for their crimes against the gov't (the people), the incontrovetible proof therein speaks to why regulations and laws are absolutely necessary to protect the public.
We as consumers are responsible for the choices we make on the product and services we pay for. However, there is only so much we can do as consumers that will protect us from the likes of those that would exploit any and all types of "deregulating" that occurs when businesses want to squeeze more profit out of us at the expense of the air we breathe, the water we drink, the monies we get cheated out of and of the daily grand theft that occurs at all levels of gov't.
I would rather pay more in tax to protect my interests as a consumer, investor and citizen than pay more just to line the pockets of businesses who have no problem with cheating the consumer and the gov't whose duty is to protect the general welfare of the public it represents.
