no they'll be fired....and some industry will be moved to Laos, Myanmar, Cambodia....
Government mandated salaries above the value of the work leads to unemployment. If there is full employment the salaries increase on themself...for many years in China they increased 10% every year. Of course government would need to reduce cheap labor from Myanmar and Cambodia so there is a shortage in Thailand.
If you want that the poor people can buy more than reduce the taxes that hit the poor people most. And stop the mismanagement for the electric (but here government has done something for the poor.....in a stupid way but they did something).
