The “problem” IS political. Without the politics staying exactly the same, the problem would not be able to continue unabated.
All it would take is for France, Germany, or Britain in particular (as Europe’s most powerful members) to change policy so that ILLEGAL immigrants (NOT “migrants” which de-criminalizes them) get treated as criminals should be treated. Rounded up and either incarcerated (no papers) or deported at cost to them (rich, with papers).
Britain need only change it’s taxation and benefits policies to achieve the same ends.
(1) If you were not born in Britain, then you cannot have a tax code
(2) WIthout a tax code, you get a temporary work permit/green card style authorization, and pay emergency taxes from commencing work until your kids born here have grown up to be 18, and they get a job. They will be entitled to tax allowances, etc. but by this point, the original immigrating generation will have paid their full way for such “entitlements”.
(3) No housing benefits or tax credits are payable to someone who merely has a work permit, rather than “indefinite leave to remain”.
(4) Actual “Asylum seekers” will be required to become apostates as part of the process of becoming a British citizen. They either want out of their old regime - or they don’t.
(5) Local employers not being able to catapult new arrivals into minimum waged “jobs”, will either have to raise wages to encourage someone not on benefits to move into the job, or pay enough so it’s worth someone already on benefits giving them up to do this job. No one even talks about the inherant danger to the public that putting someone who can barely speak English into a “job” that involves operating some possible hazardous working practice in full presence of the public at large. Slipped on a floor lately? - Floor might not have been cleaned with the correct chemicals. Got MRSA in a hospital of late? - Have you seen the way the no-speke-English cleaners wipe down bedside tables with the same cloth they’ve just wiped the sluice down with? 
(6) Housing Benefits: Scrap them, and introduce a tax on unlet properties. Landlords will then be forced to let their properties at prices ordinary workers can afford to pay out of their wages only OR will be forced to dump their properties on the market - depressing prices for the type of property that was intended for mass letting only rather than the wider market. Such a “vacant property tax” would also cream some serious dosh off the moneylaunderers with their vacant yuppie flat moneyboxes they own in London in particular.
I predict very few landlords will stand still and say “■■■■■■■■, I’ll keep my overpriced let vacant, and pay the tax until the next government repeals this tax I voted Tory to prevent”……
The Tories only won power because they’ve learned to lie better than Blair could for Labour, and turned the tables back. They are still all damned liars, who just won’t ■■■■ off the correct group in society to heal the rest of society’s wounds.
If we don’t have any game-altering policies before long - it will take “new arrivals” mudering a few toffs and their families before the political pressure builds up once more for a fresh opportunity to get done what needs to be done here. Britain is NOT for free. We are NOT wealthy enough to work for relatively low pay, and then pay our taxes for people that do not deserve to receive any help from Britain at all - declaring their continued hate and contempt for Britain as they do. How many “decent” new arrivals have shopped the “criminal” elements among their “own communities” for example? There shouldn’t actually be any “own communities”. Once here, you get with the British programme, or you get out again. It’s enough to have let so many illegal migrants slip through the net already without so many of them being hostile to other Brits already here as well!
and that’s not a lot of highways agency! 
do you believe that?
