Take a close look at the gig economy. On the one hand the positive is that it's flexible work so great for students etc.
On the other hand, people are working in poor conditions or way above legal amount of hours for a pittance. Many Brits work these jobs full time or alongside their main or several other jobs. This is just to be able to have some money in their pockets after bills rent and utilities.
Most importantly, one job does not pay them enough to live.
In these jobs many Brits work alongside foreigners and Eastern Europeans, so this 'Brits are lazy' rhetoric, when actually at the bottom of the working ladder one is often thrown together with everyone else does not stand up.
Then Brits who choose not to kill themselves working for crap pay are 'lazy' this propaganda works for big business.
Take a look at the construction industry. It is harder for workers to get decent pay, especially doing HA or Council contract work. They have been undermined by the bosses, companies and the govt who will happily pay less to foreign workers, than pay their fellow Brits for doing the same skilled work.
The working class Brit is royally shafted on all sides, then has to put up with this 'brits are workshy' crap from their right wing 'betters' above and their left wing 'friends' below, who are so eager to appear inclusive, they have made their core audience excluded.
Shat on on all sides. Then they wonder why Brexit happened.
