It is a good thing.
The consumer is a small entity. A rich international company with established brand is a giant.
A giant has deep pockets and an in-house legal department plus batteries of high priced external lawyers as consultants.
A big corporation can and does bully its way around and threaten a lone citizen consumer.
In Singapore, we have the unsavoury and obnoxious historical fact of Mr. T. T. Durai & the NKF doing that to lone citizens.
He only lost when he mis-calculated that strong support from the-then Mrs Prime Minister will be enough to frighten SPH, which is another giant corporation with its strong board of powerful beings such as Lim Kim San and Tony Tan (current President) and even deeper pockets than the NKF, to hire top lawyers.
In America class action suit has been used by Ralph Nader to get the US motor manufacturers to improve the safety of their vehicles.
